I'm glad that Dave mentioned the Main Stand side linesman as he was doing my head in as well. Couldn't spot the blatant foul on Trent in the second half from a few yards but could see a slight deflection on the opposite side of the pitch from 30 yards or so away.
You could see why the Chelsea players carried on the way they did and it had the desired effect. The three minutes injury time (not that we would have scored even if he had added on thirty three) summed it up. They spent so long time wasting in the second half yet none of it was added on.
