IBM is famous for providing its Watson Artificial Intelligence to the Wimbledon tennis tournament. But we sought to do something completely different and give Watson the ultimate test. We wondered if it could help a struggling, grassroots football team up its game. Over the course of the 2018/19 season we documented what happened at Leatherhead FC to see if it could change their fortunes. Because if AI can help this team raise their game it can help any team raise their game.
