The researchers examined the players' executive functions – cognitive abilities such as decision-making, working memory and flexibility – and were able to link the results to actual performance on the pitch. Players who performed high in the tests accounted for more goals, assists and minutes played, which shows a clear connection between psychological factors and football performance. This is one of several studies that form the basis of our services. By using similar testing methods, we can now provide clubs with decision support that increases the likelihood of successful signings, talent development and better squad balance.
