Data Mining for Strategy development in Football

The application of data mining and analysis techniques is not new to football. However, it has not been exploited to its potential by football clubs in India.
A team of Industrial Engineering students from College of Engineering Trivandrum, completed a project on Football Analytics. The football analytics system developed includes methods for data collection from matches, algorithms to extract meaningful results and patterns of play from the data and methods of visualization of the findings. The patterns in passing and movement of players can be used as a tool for building the right strategy against the opposition. This vital information about the team and players makes the difference between winning and losing.
Attached below is the report of the match between Atletico Paranaense and Shamrock Rovers which was analysed using this system.

The statistics generated reveals areas of strength and weaknesses of the team. The visualisation of passes show patterns of play of the team and the players. The distance run by players and their speed profile can be used to substitute the players that show a below average performance. The passing combination reveals the sync between different players around whom the game revolves.
