To me, he's a bit of a symbol of Everton at the moment. He's obviously a player who plays only for himself, and gives a damn about the team. If we win, and he does not score goals, then he whines. He argues with his teammates about taking penalties, free kicks, etc. Has mostly a negative body language.
As a player, he is ok and has his moments. However, he lacks the football intelligence, awareness, and technique to be able to utilize space. For example. in the first half, he had a great opportunity to center a pass through to AG, so that he had been alone with the goalkeeper, but had the wrong body position and looked down on the ball.
Of course he will score many goals when he plays with Neymar, etc., and in part he scores goals for Everton, but he does not have the ability to make his teammates better. He also does not have the ability to lift his teammates when the team is having a hard time, instead he only reinforces the negative.
