We're definitely the in form team at the moment, while they're more or less out of form. That doesn't mean nothing though, simply because we will try to dominate the ball as always whereas City will be on the counter attack.
Really hope it doesn't turn out to be one of those matches where we're clear favorites but suddenly play like shit while City somehow become good again.
Sadly it's that way with every other English team. Not only Chelsea and City but even Arsenal and Liverpool don't really have a lot of English players in their first xi.
