The paper investigates the variety of peer effects on individual performance in a team sport. The individual performance of more than 5,000 soccer players, from 234 teams, between 2010 and 2015, is measured with the help of the FIFA video game simulator developed by EA Sports. The study reveals positive peer effects on individual performance although the marginal benefit decreases. Additionally, team cohesion contributes to an improvement of players’ ranking.
