Arsenal boss Arsene Wenger says Sunderland pushed the boundaries of the rules in yesterday's clash.

The Gunners were undone by a scrambled goal from Darren Bent.

And on Sunderland's aggression, Wenger said: "You expect that. I have a little to be done because they tried more to destroy and we had more of the ball. So I think that they tried to stop us from playing, sometimes on the fringe of the rule, but that's part of the game."
