Arsenal boss Arsene Wenger believes Mesut Ozil can make a difference against Champions League opponents Bayern Munich.

Wenger claims the challenge facing the Gunners will have a more attacking edge, following their acquisition of Real Madrid ace Ozil.

"We are different and they are different," said Wenger.

"How much different are they? I don't know but they look to play a bit more adventurously and more going forward, and we do as well I must say.

"We certainly have more offensive potential with [Mesut] Ozil coming in and we have to find our defensive security back which we have lost over the weekend, but it will be a very interesting challenge."
