It was only 3-0 before the break, with Arjen Robben, Mario Gomez and Thomas Muller on target for the Bavarians. A new team was introduced at half time and Croatian forward Ivica Olic hit five goals, Franck Ribery and Nils Petersen scored twice and Diego Contento added one. The game witnessed the return of Germany midfield star Bastian Schweinsteiger, who is expected to feature against Ahli at the weekend.
