It's not only that though, because his needless mistakes, own goals aside(!), single-handedly cost us about 4 goals last season. Whether it was tripping over his own feet, passing directly to the striker, terrible mis-judging the flight of the ball and getting horrible caught out, being flat-footed and losing his man, he did it all. An absolute calamity of a defender, and the very worst that we've got. And we have a BAD bunch of centre halves.
So right, the couple of goals he scored do not compensate for all the poor play you highlight. Need to get rid.
