From the left side, Bastian Schweinsteiger's cross picked out Muller, whose header skipped off the turf, struck the underside of thebar and nestled inthenet.
Jupp Heynckes' side continued to press after the half-time break when Stefan Kiessling saw his shot from the left tipped over thebar by Drobny while Ramos had the ball inthenet again for the home side but the effort was chalked off after the assistant referee flagged for offside.
The key moment of the game was probably Sexton's goal miss early inthe second half when he blazed over thebar for a point when thenet looked certain to bulge.
