Graham Potter has been handed a massive injury boost at a vital time ahead of Chelsea's London derby with fierce rivals Arsenal.
The new boss has been working with a depleted squad and immense fitness issues since he arrived in September and those problems have only gotten worse as the weeks have gone on. Potter has just five first team defenders fit - making a back five from the start a risky strategy - and is also balancing midfield fatigue as well.
When Potter chose to play with an almost fully-fit squad against Dinamo Zagreb on Wednesday it raised questions, and it almost came back to bite him more than the sting already hurts.
