Having opened their European campaign with consecutive defeats to Dynamo Zagreb and Olympiacos, the Gunners returned to form with a 2-0 victory over an in-form Bayern side courtesy of second-half goals from Olivier Giroud and Mesut Ozil.

It was a header from the England forward which drew a stunning first-half save from Bayern's Manuel Neuer - although the World Cup winner was at fault for Arsenal's opener.

Ozil completed the win in stoppage time as the fifth official did well to spot his shot had crept over the line despite Neuer's best efforts - with Wenger delighted with the display of his team.
"We had an absolute necessity to win the game and we did it in an intense and disciplined way," he said.
"It was a top-level game between two top-level teams. Bayern had more possession than us but we decided to make it tight in our final third and catch them on the break.

Despite the win, Arsenal remain third in Group F and are three points adrift of both Bayern and Olympiacos - who were victors in Croatia.
