Per Mertesacker is hoping that Arsenal can build on their victory over Manchester United when they square off against Bayern Munich in their next Champions League outing.

Following a difficult week which saw them lose to Olympiakos in Europe, Arsenal managed to hit back at their critics by claiming a fine 3-0 victory over United on Sunday.

The win has certainly filled the Gunners with confidence Mertesacker is hopeful that his side can continue their fine form when they host German giants Bayern in the all-important Champions League clash on October 20.

Mertesacker said: "We are pleased that we have [won] after the Champions League debacle, and you could see how much the team wanted to respond.

"As a team you try and remind yourself of what you can achieve and you could see that we have a lot of confidence. I hope that we can display that again in two weeks."
