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."
