Poll: What Bayern Munich player is most important to that squad?

In about 24 hours now Chelsea FC will play the biggest game in the history of the club. I think we're all pretty sure who we'll be seeing in the Chelsea starting lineup, and the Bayern lineup seems more or less set as well. That got me thinking about the players they'll certainly be sending out on Saturday. Franck Ribery, Mario Gomez, Arjen Robben, Bastian Schweinsteiger, Toni Kroos, Philipp Lahm, and Manuel Neuer are all very good players that could absolutely turn this match.

I'm going to pose the question to you then. Which Bayern player would you consider most important to their club? For this discussion, don't take age or pay into account, just the player's impact on the game being played at present. I'm really curious to see the results from this one, as Bayern have a very good squad overall. Vote in the poll and discuss in the comments section below.
