Arsenal got off to a dream start when Giroud tapped in Theo Walcott's low cross from close range with three minutes on the clock.

Bayern looked to level just minutes later, but Luiz Gustavo lashed his effort well over the crossbar.

The hosts started to control possession midway through the half and they had another attempt at goal on 27 minutes when Toni Kroos's shot from the edge of the box was kept out by Lukas Fabianski.

Bayern had one final chance of the half as Thomas Muller shot wide.
