I think you guys are jumping on Big Sam a bit too much. He is slower of cos but he never had pace anyway. He never let us down last season when he had a game. No doubt he gave away the penalty against Porto but the whole team was poor then in that early period, so why put all the blame on him? I don't see anyway slagging off Arbeloa for his tug on Kanu? I'm sure Sami will bounce back for us in the next game.
Do we need another backup CB? Of cos, but that's a separate question.
