Arsène Wenger has praised his team for responding well to a potentially "deadly" goal at Stamford Bridge on Saturday - but he wants them to defend better.

John Terry got ahead of Per Mertesacker to bundle Chelsea into a 2-1 lead just moments before half time at the weekend but Arsenal regrouped and were ahead within ten minutes of the restart before running out 5-3 winners.

Wenger believes that their second-half fightback showed the spirit within his squad but he would rather avoid defensive mistakes in the first place.

"There is still some room for improvement defensively," he said. "In the first half we were too vulnerable, Chelsea missed some chances, so we can still improve. But it is important to go away from home and score five at Chelsea, because not many teams can do that.

"It is hard to watch defensively beause we gave them too much room, too much in midfield, we were exposed on long balls over the top, so you can only hope you do not pay too much for it. And after it was a bit of a test mentally because conceding before half time can be deadly, but the way we responded was very pleasant.

"I feel as well a team like Chelsea play in an offensive style, with top quality players to do it. They play with Mata, Torres, Sturridge, Ramires in the box and Cole and Bosingwa as wingers. When you do not manage to block them they inevitably make chances."
