If a player is agressive then he will tackle more and probably get more cards.
If a player is calm they will pass smoothly and score goals with ease.
If a player is determined they will go for every ball and could get into trouble.
Thats how personality affects sports performance in Soccer (Football).
Personality can affect sports in many ways. Lets say if someone is very cocky. That will make them work hard to prove their point of being cocky. If someone is very shy then they won't want any pressure and won't perform well. For example; if there's a Basketball game going on. There's 1 second left. You're team is down by 1. If someone is very cocky and brave they will be willing to take that final game winning shot. If the person is shy and doesn't have much courage they might crack under pressure and deny to take the shot.
