that is simple bullshit he was one of the better players but ppl forget quickly or judge players from the past or based on their "rush" or immature nature which is gone, can't really get how people still can think that
..
one or two bad games and people go overboard and I believe one of those "bad games" were when he got carried away and played on the edge against that liverpool cnut Gerrard who was scything our players that game so I was actually proud when he finished the game without sending off giving 150% like always and like none of other players. The second incident was against David Luiz I believe and it was little bit stupid but Sideshow Bob was filming it and it was pretty embarrasing from him... anyway he was doing okay overall and had at least couple of MOTM performances IIRC, whether it was due to our overall inability to do something in attack or nonexistent midfield, he set his standard higher than majority of the players.
So this criticism is really laughable, whether we should replace him for his inability to stay fit it's another question but he usually plays well when he plays.
