The first period brought just the one goal with Thomas Muller heading Bayern into the lead after 25 minutes. It was 2-0 in the early stages of the second half, however, when Mario Gomez tapped home from another set piece.
The scoring was not finished, however, as Muller added his second late on to secure a comprehensive win.
