Bayern Munich host defending champions Borussia Dortmund tonight in a clash of mammoth proportions. Bayern will be without the services of Bastian Schweinsteiger and Anatoliy Tymoschuk, but have Arjen Robben returning to action. Heynckes will probably decide to start the Dutchman on the bench and expect him to run riot against the Dortmund back four when he comes on. Dortmund's only player on the injury list is center back Neven Subotic and he will be replaced by Felipe Santana.
Dortmund beat Bayern in both ties last season, but are without the services of the ever so influential Nuri Sahin, who moved to Real Madrid this summer. The other goalscorer for Dortmund over the two games last season, Lucas Barrios, will probably start on the bench yet again. Both teams are brimming with quality and this is proving to be a mouth watering clash. Both teams are not the most efficient defensive units, so if you're a neutral, this could prove to be a highly enjoyable goal-fest.
Let's take a look at which personal battles could prove to be crucial in tonight's game.
