I think it would be the most stupid decision from UEFA to cancel all of the yellow cards. Yellow card is a punishment for a non-professional behavior. You can't motivate such behavior.
But Chelsea, I guess Chelsea has turned to be a team, which doesn't really care about any absent players. If it's their day, then they will win, if not, Terry and Ivanovic wouldn't help much. A little bit of a strange season for them, to be honest. A lot of credit to Di Matteo though.
And Bayern, well, the only team that overperformed (yes, I mean overperformed) Real Madrid this year. They don't depend much on defence, so forget about the suspended players: Gomez scores his goal anyway.
My prediction for this match is that the famous statement of Gary Lineker is going to be quite relevant...
