How Data Analysis and Information Systems Are Changing Football

Introduction:

It makes sense to start this piece with two quotes from German football journalist and author of a recent book “Football Hackers”, Christoph Biermann who said, “data is part of an ongoing evolution that changes football from a game of opinions into one of knowledge. (Biermann 2019, pg8) The writer also makes the strong point that “the future of football will not simply belong to those with the best data, but those who draw the best conclusions from the information at their disposal.” (Biermann 2019, pg8) This piece will discuss how data analytics and information systems have impacted the world of football and the industries around it over the last few decades. This piece will analyse how data has change football tactics, scouting of players, player fitness and the betting industry.  Who is using this data? How is it being used, and why?

Definitions, History and Influences
“Data analytics is the science of analysing raw data in order to make conclusions about that information.” (Investopedia 2019) Football, like other sports, is providing analysts with an ever-growing amount of raw data to investigate and interpret. This data along with modern-day Information systems which is “an integrated set of components for collecting, storing, and processing data and for providing information, knowledge, and digital products,” (Encyclopædia Britannica 2017) have built the data culture we see in football in 2019.

(Sandle 2018) tells us that “the rate at which knowledge is becoming available is doubling every 12 months and on a curve predicted to rise even faster.” See graph 1 below for a representation of this. While not a perfect 100% increase, the increase is stark.





With this in mind, it is no surprise of the growing need for Information systems which can quickly process data and present it in an easy and understandable way. It is also no surprise that information is playing a more prominent and more significant role in sport every day. Data in sport goes back to the beginning of modern sport itself with information like how many of the previous five games a team won. The raw data that is transformed into information systems we see in football nowadays is a relatively new phenomenon. Much of its influence is from American sports such as hockey, basketball and baseball. One example of the explosion of data in American sports in the book “The Art of Winning an Unfair Game” where the author Michael Lewis wrote a book about how a baseball team the Oakland A’s closed the gap between themselves and the wealthier franchises by using analytics to find undervalued players.  The author credits the book to a simple question; “How did one of the poorest teams in baseball, the Oakland Athletics, win so many games?”


Who are the Main Football Data Providers and Users of Information Systems?
On stats.nba.com, users can view and interpret players statistics such as running speeds, shots taken, the place from where shots and passes happened, head to head records, player heat maps, player comparison and player impact tools. American sports have for a long time taken real-time data that may not seem like much at the time, but when gathered consistently and over long periods can explain sports in incredible detail. This data can then be transformed into information to be interpreted just like any business would use information like a sales report. We see unstructured data such as video turned into structured data, that with the help of information systems can be presented in charts, graphs, tables and dashboards.

Football now has many companies offering in-depth statistics about football with the help of information systems. Such sources include transfermarkt.com, football-observatory.com, whoscored.com, optasports.com, smarterscout.com and many more. All of this information is used by fans and clubs alike to gain a better understanding of the game. It also helps them gain an advantage over the competition on and off the pitch. See Graph 2 to see how New York based company smarterscout have used a dashboard to breakdown the Premier League performances of Norwich FC right-back Max Aarons. This dashboard is an example of structured data.

One reason why statistics were brought into American sports sooner than football a game which has often seen to be dominated by Europe and South America, was that the data was easy to interpret due to a straightforward reason. It had natural breaks, or at least that was the argument for sports like American football, baseball and even the English sport of cricket. According to (Coles 2013) football was a dynamic sport seen as “is too fluid, too fast and too random to assess open play” to implement such strict data collection. It was, therefore, a game impossible to examine from an imperial standpoint. 


Role of Information Systems Play Off The Field
In the fast and demanding world of football clubs need accurate knowledge quickly. Information Technology which “helps to optimize the use of scarce resources through intelligent information support for decision making, helps further in its implementation by support co-ordination effort without wasteful delays.” (O Brien & Marakas 2010) Data can now be the difference in success and failure on and off the pitch. But on the other hand according, to (Kishore, Zang, Ramesh 2004) “information systems are only a particular type of work system that support other organizational work systems.”

It is easy to forget that the super clubs like Barcelona and Manchester United are much more than 11 players who play on a Saturday. They are large businesses with revenues in the hundreds of millions. In 2018, Real Madrid had a revenue of over €750 million. (Deloitte 2019) With this comes many responsibilities such as marketing and customer service. “All football clubs now utilise the internet as a direct channel for accessing their fans and providing them with the necessary information. “This process allows fans with online capabilities to access up-to-date information by accessing the official club website.” (Cleland 2011) This has expanded in recent years to social media where many clubs have millions of followers on Twitter, Facebook and Instagram. Clubs can use Information Systems to automatically send updates to fans via email or by an app on topics such as ticket prices, travel arrangements, and club updates. Information Systems could also be used within clubs to set up services such as instant messaging, management of documents, cash management and email. (Green 1999) pointed out in his piece Football Information Services that “football clubs are more dependent than ever on information services to market their particular brand.” (Kishore, Zang, Ramesh 2004) backed this up further when they said that “workflow is central to integrative business information systems.” Football clubs would find it impossible to manage such volumes of information without Information systems.

How Football Data Is Collected
Information Systems also make the storing of information much more efficient and fast. For example, companies such as Titansensors have developed a GPS tracker that measures players performance in real time. The sensors measure data such as sprint distance, sprint speed, muscle soreness and conditioning scores. (TitanSensor 2019) Observe Table 3 to see all of the offered metrics. The introduction of such technology is seen by many as the “one of the most significant advances in football over the last decade.” (Medium 2019) The new technology has not just increased the amount of data that coaches have but it is also reduced the time needed to analyse the information.

Companies such as Statszone.tiki-taka.co use their app to provide anyone willing to pay the monthly fee with in-depth stats of football games. It is thanks to the efficiency of modern-day information systems, real-time data collection and internet speeds that they offer their service in real-time with minute by minute change to metrics on the app as they change on the pitch. Information is then presented on easy to understand dashboards. See graphs 4-6 below as an example of in-depth statistics of Dries Mertens as Napoli beat Liverpool 2-0 in Italy on September 17th, 2019. Graph 4 presents the 24 successful and seven unsuccessful passes the Belgian made. Graph 5 shows the five times he retrieved the ball during the game and where the actions took place. Finally, graph six shows the crosses the player attempted during the game. Much of the data industry is possible due to a company known as Opta. They specialise in the collection of sports data. According to (Opta 2019) “data is recorded, analysed and distributed using a bespoke system that allow us to provide our data quickly, reliably and securely to customers through a range of solutions.”

How It Impacts In-Game Tactics And Coaching
JOHAN Sports are another business who offer GPS tracker services to professional football clubs. JOHAN Sports promise that their service will help identify when players have "an increased risk of injury" or to "create the ideal periodization schedule with the use of data" and "information on how to adjust training load". When football coaches can examine the fitness of levels of their players in real-time, this unstructured data quickly becomes structured data leading to better decision making. Sunderland fitness coach called a similar technology from STATsports is "quite an integral part of the whole backroom team's work." (Wright 2016) Moreover, that "the technology allows clubs like Sunderland to tailor their players' workloads individually and fine-tune their training through the week" (Wright 2016) This allows clubs to push players to their limits but also to inform players to rest when needed to prevent injury.

As mentioned already, in-game statistics can impact how a team plays, who starts a game, for formation is used and so on. These are all examples of decision making. The introduction of statistics into the world of football has been a game-changer. (Dario 2002) argued that “advances in information technology have made it possible to augment and improve the feedback athletes receive during training and competition.”  However, to think it is just a recent phenomenon would be incorrect.

Sam Allardyce and Bolton
One often forgotten example is Sam Allardyce and Bolton Wanderers. Under the often-controversial Englishman, Bolton reached promotion to the Premier League and eventually UEFA Cup football. The side played old fashioned football which involved kicking the ball from one end of the field to the other. A style often frowned upon due to its simplistic nature and lack of skill. However, for Bolton, their style was based on detailed statistics, especially for the time. Allardyce, also known as “Big Sam” was at the club from 1999 to 2007.

Back then Information Systems were not what they were today but despite this Allardyce used statistics to improve Bolton’s chances in the Premier League. (Newmann 2015) and writer Michael Cox in his book “The Mixer” talk about how Sam’s time in the USA with the Tampa Bay Rowdies changed his perspective on sport and the role data could play. (Newmann 2015) By working with data collection company Prozone, Bolton realised that if they “had to stop the opposition from scoring in at least 16 of their 38 league games to avoid relegation; if Bolton scored first they had a 70% chance of winning; set-pieces accounted for almost 33% of all goals scored; in-swinging crosses were more effective than out-swingers; and they had an 80% chance of avoiding defeat if they outran their opposition at speeds above 5.5m per second.” These statistics and more were used to dictate how Bolton played. It helped the decision makers maximise the resources they had. But marrying their inputs such as personnel of players and coaching staff with data, the team produced a surprisingly high level of output.



How Data Almost Made Chelsea European Champions
(Dario 2002) Claimed that “video technology has significantly influenced training methods”. A famous example of this came in the 2008 Champions League Final penalty shootout between Manchester United and Chelsea. In 2003 Basque economists Ignacio Palacious-Huerta published his paper “Professional play Minimax” where he tracked statistical patterns in penalty taking. Ignacio had followed the pattern of Manchester United and passed his findings onto Chelsea. Findings that, if not for a slip on a rainy night in Moscow, would have many Chelsea European champions. This conclusion is game theory which “is the process of modeling the strategic interaction between two or more players in a situation containing set rules and outcomes. (Mcnulty 2019) Huerta’s finding revealed that Manchester United goalkeeper Edwin Van der Saar assumed those penalty takers would shoot across their body Meaning a right-footer would to their right and the goalkeepers left.  Therefore, the Chelsea players should shoot to their “unnatural side” He also learned that “Ronaldo often stops in the run-up to the ball. If he stops, he is likely (85%) to kick to the right-hand side of the goalkeeper.” (Kuper/Szymanski 2014). Ronaldo did stop, and as predicted went to his left, and the goalkeeper saved it. The ability to analyse data due to the use of Information systems and the oppurtunity to study shootouts, economist Ignacio Palacious-Huerta almost made Chelsea European champions.

Lastly, there is the surprising data that one of the world’s best players Lionel Messi creates more space if he stands or jobs than if he spirts. With this knowledge, the Argentine can conserve his energy, not be so tired in front of goal, which we can assume increased his scoring rate. There is an argument to say that if Lionel Messi ran more, he would be less effective at completing his main task of scoring goals.

Football Scouting
As already mentioned, Information Systems are “an integrated set of components for collecting, storing, and processing data and for providing information, knowledge, and digital products,” (Encyclopædia Britannica 2017). In 2019 with the help of Information systems, AI, and machine learning football clubs are scouting players from a more analytical perspective. Clubs can use this information to scout more efficiently with the with use of easy to understand information systems such as dashboards.

In an interview with the Financial Times (FT), Ted Knutson, co-founder and chief executive of StatsBomb said; “Manchester City just don’t sign bad attackers any more either; they signed De Bruyne, Sterling, and Sané back-to-back-to-back, who were among the very best choices [according to the data] each time.” (Burn-Murdoch 2018). Scouting can help clubs identify players who are undervalued often due to or a lack of physical attributes with the use of statistics.

According to the (Independent 2016), Leicester City Football Club asked their “analytics team to look for metrics such as most interceptions, tackles and forward passes per 90 minutes across Europe’s top leagues.” They quickly discover little known 5ft 6ins N’Gole Kanté. Leicester found a player that would not just perform well in a league winning side, but also make them a profit. Leicester sold the player one year later for £32 million, making a £26.4 million profit. He has since gone on to win the PFA Premier League player of the year. (BBC 2017) He (Kanté) was discovered due to scouts looking at the statistics and not the appearance of the diminutive Frenchman. At 5ft 6ins, his type of build was often overlooked in the past. Raw statistics is only numbers on a screen, but this, coupled with information systems and IT, these statistics such as video, can be turned into valuable information. The processing and storing capabilities of the software behind companies such as wyscout has changed football scouting forever. Perhaps other industries and not just other sports can use similar methods to improve their HR and recruitment departments. This hope may be challenging to do with GDPR within the European Union, but football has proven that the technology is there.


VAR & Goal Line Technology
Goal-line technology (GLT) has been an instant hit in football. A technology similar to that in tennis and cricket is an excellent example of information systems processing data. The results of GLT need to be extremely quick and accurate. According to (FIFA 2018), the “technology adopts seven high-speed cameras per goal and “the images are sent to a computer and analysed in real-time.” As soon as the ball crosses the line, a signal will be sent to the referee’s watch, letting them know it is a goal. This fact is an example of information systems providing real-time information that is instantly solving a problem.
Video Assistant Referee (VAR) has been less successful.  However, is none the less a form of data collection and information systems. If a referee is unsure about a critical decision in a game, he can ask or be advised to use VAR. Many fans have complained that the system is not quick enough. This piece of information is perhaps an example of where information systems need to be improved to collect and provide data quicker for customers. According to Premier League referee VAR “has made four mistakes so far during the Premier League season. (Sky Sports 2019)

Impact on Betting:
There seems to be a lack of research into this topic. But there is no doubt that football fans nowadays are a lot more educated about the sport than they were in the past. This is somewhat thanks to TV punditry and the rise of subscription television, but it is mainly down to the football data analysis that has grown from the small group of football statistic blogs.   and betting companies have long had the advantage of asymmetry information. The (American Economic Review 2003) suggest this is when “buyers and sellers commonly process difficult, and not identical information.” This means that a seller of a service may have a much better understanding of a product than a buyer. With the increase of data, this gap has decreased. Betting companies benefit from having more knowledge. They will have to find new ways to stay ahead. Which will likely lead to an even greater need for information and increased sophistication of information systems and data analytics. 2015 saw the introduction of UK betting company where users can buy stocks called “features” in football players. On the platform, users are essentially betting on the future performance of a player rather than betting on individual results. If the Index is to go mainstream, it will further complicate sports betting and the world of football as a whole. (Football Index 2019) The index uses information systems and cloud computing to gather information in real time. This information includes headlines from UK newspapers to calculate media dividends for customers. Match day information to inform match day dividends with their live ranking system.  See graph 8 and 9 below.

Conclusions:
The world is seeing rapid growth in date and the football industry is no different. To be successful in the future football clubs like any other business will be rewarded for taking this data and turning it into useful information. The role of Information systems will be likely to continue to grow. Information System operators will need to continue to improve their system’s ability to collect, store and process data. These systems will continue to create information, knowledge and wisdom from these data inputs. IS will likely integrate itself further into football scouting, the transfer market, football tactics and the betting industry.
