The biggest issue with me Iwobi, for me is just his incapacity to close down or move towards a ball to collect it. There was a moment yesterday when the ball was played to him and he just stood still, never moved a muscle until the City full back strolled past him and took the ball. He seems unaware of his surroundings all the time, whether he has the ball or not. His decisions when covering Digne or Coleman seem off and seems to have very little understanding of his fellow players, or what they're going to do. There maybe an answer as to why, and personally I think its because he just doesn't have the concentration required to be a top class footballer.
