We know how good we are but we cannot just hope to beat Arsenal - Bayern's Lahm
The German giants take a 3-1 advantage into the Round of 16 second leg tomorrow night and although Lahm is confident, he knows very well that Bayern will have to perform in order to see of a Gunners side who will come to the Allianz Arena with an attacking mindset.
"We know how good we are and we have a lot of confidence, but we do not expect to win everything," said Lahm.
"We must work hard and we must be focused.
"Of course Arsenal must attack, they have to play catch up, but we must also attack and cannot just hope to win."
