it was 5-2, to the German league Champions.
You are right Chelsea had made some changes, most notably leaving out Drogba, and Mata - but replacing them with Ramirez (so-so), and then Fernando Torres (say what you want about that), and then lost handedly to an 7/8th place Liverpool club.
Weirder things have happened than Chelsea willing the final (hell, Villareal made it to the quarters i believe just a few years ago), but Bayern is vastly more talented at pretty much every position save for CB, and marginally at ST depending on the day of the week.
