Can't help but feel his best position on the pitch would be as a false 9 with wide men overlapping where his wastefulness isn't so costly, and he can't do as many unwise, ill-thought out actions that put the team in jeopardy.
The better the teams we face, the worse he becomes because he sees less of the ball and every errant or wild action looks far worse, like he's lacking intelligence for even attempting such low percentage actions.
I think a lot of that is negated by purposely making him the player who is
supposed to deliver the final action rather than being a secondary cog in the machine who is supposed to pick and choose his moments and not treat the ball like it's a bomb he has to get rid of as quickly as possible no matter the circumstance.
I think
@Yagami is right, though. He's not the type of player you see in teams at the very top of the food chain and I think his limitations become obvious when he's up against very good defensive midfielders or very aggressive, organised pressing.
