Because he plays for Manchester United, every little thing he does on the pitch is highlighted and analysed, especially mistakes. People who don't rate him are focusing or the two or three occasions where he has made a significant mistake which has been intensely highlighted and talked about. Nobody remembers the other 98% of matches he has played for Manchester United where he has been rock steady and not done anything wrong. He is a class player,more than worthy of a place in our back four, a good honest pro too who will give us 100% if he signs.
