Arsene Wenger believes Arsenal must look to attack when they take on Bayern Munich in the Champions League on Tuesday night.

The Gunners suffered surprising defeats in their opening two Champions League fixtures against Dinamo Zagreb and Olympiakos, leaving them sitting last in Group F.

Now Wenger believes Arsenal can afford to get nothing less than all three points from their clash with Bayern, as they look to revive their hopes of qualifying for the knockout stages.

"We are now in a position where we can focus really and give everything on Tuesday night," Wenger said.

"I will have to see how we prepare for this game now and decide what we really want to do. The confidence level is there, the required result is there as well, because we know exactly what is needed - a 0-0 is not even a good result. To score goals, we have to attack.

"What we want to do is play up to our level, because that will be needed - we play against a big team.

"We feel a bit that the pain inflicted [in Europe] was a bit by ourselves, maybe subconsciously we thought, 'Anyway we will win these'. Now to correct that we need a great performance."
