While using him, I had him up front with mid Cruyff and prime Jairzinho, he feels insane on the ball and is incredibly strong. Within the 5 matches I played, I managed to pull off a 0.00 expected goal and a bicycle kick goal. Payet and Jairzinho feel really similar, with Payet faster and stronger on the ball whereas Jairzinho's shooting is better. I played him in a few different positions, from left centre forward to striker, he feels great in both and could easily play in cam too. You should really take advantage of the strength in a striker or winger position though.
Dribbling is impeccable
Shooting is godly
Is okay with headers, nothing insane.
Doesn't have the best stamina but it's nothing awful either.
