Let's look at some of the potential players Chelsea could use (Loftus-Cheek is injured) :
Caballero / Green
Moses
Zappacosta
Cahill
Christiansen
Ampadu
Emerson
Fabregas
Drinkwater
Barkley
Giroud or Morata
Hudson-Odoi
Whatever team they put out it's going to be strong. They like us, now have some depth even though there is a clear quality drop-off, especially up front where they will likely be forced into using Willian unless they delve into the youth squads.
Rudiger and Pedro have slight injuries and are likely to be rested anyway.
There's depth, but I fancy our second string against theirs. My biggest worry is Barkley. Not because of his talent, but because I can see him throwing himself into reckless challenges to prove the old 'once a blue' adage.
