Wenger, though, refuted suggestions his squad was in need of reinforcements.
"I don't look for anybody," insisted the Arsenal manager.
"The last excuse you should look for when a team that has won many games this season doesn't win is to say you should buy players."
Wenger maintained: "I don't think we missed Kolo either: Philippe [Senderos] wasn't involved in the set-piece for the goal.
"We just didn't defend it well and that's how we were punished."
