Bayern Munich attacking midfielder Mario Gotze has urged his side to maintain their focus, despite winning their away Champions League last-16 leg against Arsenal 2-0 on Wednesday night.

Gotze said that it was a big advantage to hold a 2-0 lead going into the return leg, but that Arsenal do have the quality to get back into the tie if Bayern let them.

"Winning 2-0 away is always an advantage and I think we can be very, very satisfied," he told UEFA.com. "But we must still remain very focused for the return leg.

"I think we would do well just to take each game as it comes. We have an important return match - we will have to concentrate hard in order to get through to the next stage. We can just be happy that we won 2-0 away. Arsenal played very, very well, and I think the most important thing is that we remain completely focused."

Toni Kroos and Thomas Muller scored Bayern's goals on the night.
