I can see where Glen is coming from Jimmy. O'Hara has never done it for me either. He had some chances and never took them. The only reason to keep him in the squad would be cos he has a good left foot which is a rare thing this days and it does give the team a much better balance than when you are playing a right footer on the left.
If we are seriously looking at improving the team/squad and playing in the CL then IMHO I think we need better than O'Hara.
