London, Oct 19 (IANS): Arsenal manager Arsene Wenger believes that his team has no choice but to play an attaking game against German football giants Bayern Munich in their Champions League encounter at the Emirates Stadium here on Tuesday.

Defeats to Dinamo Zagreb and Olympiakos mean Arsenal almost certainly need to take points from the two legs against Bayern if they are to avoid a Champions League group stage exit for the first time in 16 years.

The Bundesliga champions make the trip to London on the back of 12 straight wins, but Wenger said Arsenal's own recent performances have given them the confidence to pull off a result.

"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."

Bayern has eliminated Arsenal from the Champions League twice in the past three seasons, but Wenger seems confident of a victory this time round.

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

"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," Wenger added.
