What's his position? He's not a 10, not a 9, not a winger, not a 8.
The guy isnt a great passer, finisher or dribbler, cannot beat his man. He's a hard worker, great at defending (as a 9), and has good overall link-up play.
Did you see the sitter he missed again today? He has missed MASSIVE chances in almost all of Arsenal last 5 games, and their fans are now seeing what we knew already when they took him from us, he's decent at best. Never good enough for a top team.
