I'd go for:
Begovic (TB injured)
Azpi (rb)
Cahill / Terry
Zouma
Rahman
Matic
Ramires
Fabregas
Pedro
Hazard
Costa
Subs: Willian, Djilobodgi, Loftus Cheek, Kennedy, Traore (if Oscar still injured) Falcao, Blackman.
A blend of experience and new, fresh players. The opposition can't plan for a player they're not used to playing against, and that plus outweighs the relative lack of experience imo.
For me a question mark over JT. Yes, he has been a fantastic servant of the club, but he needs to be 100%, and if he isn't, especially considering his lack of pace, he will be targeted like Ivanovic, and will become a weak link. It's not disrespect, it's reality.
If Djilobodgi settles in, then I would possibly move Zouma into deep midfield, at the expense of an out of form Matic, or play the two together to shore up the midfield.
