Bayer Leverkusen (4-2-3-1?): Bernd Leno; Gonzalo Castro, Michal Kadlec, Omer Toprak, Stefan Reinartz; Simon Rolfes, Lars Bender; Sidney Sam, Michael Ballack, Andre Schürrle; Stefan Kiessling
Substitutes: David Yelldell, Daniel Schwaab, Manuel Friedrich, Renato Augusto, Hanno Balitsch, Erin Derdiyok, Karim Bellarabi
No John Terry (not sure why), so Petr Cech is captain, and the 4-2-3-1 is a guess (which was wrong!) based on the personnel in the starting lineup. Am really curious to see how well Torres links up with Mata and Sturridge. Also, Leverkusen's lineup is weird, but hey it's Michael Ballack time. Let's go Chelsea!
