Speaking ahead of Chelsea's match against Gent, Maresca said: "We played some games without Cole, but sure and for us, Cole is something extra that you need. We also need to think a bit to protect some players. They need that. There is a reason behind it and I think Cole needs to be protected."
THE BIGGER PICTURE
Thankfully for Chelsea, there is time to edit their squad when the initial phase of the competition ends in January. This means - if he wants to - Maresca can include Palmer for the knockout stages, providing the Blues get there.

WHAT NEXT FOR CHELSEA AND PALMER?
With Palmer watching from the stands for Chelsea's match on Thursday, he will be refreshed and ready to go for their match against Nottingham Forest on Sunday. The 22-year-old scored four times against Brighton last weekend and will be hoping to replicate that feat this weekend.
