Both are back in training, but it is unknown whether they will be fit enough to feature in the Premier League encounter.Bryan Oviedo has also trained since going off injured against Chelsea and could be available for the match.
It is likely that one of either Coleman or Oviedo will play at right-back, depending on their relative fitness. Meanwhile, McCarthy may well be rested for longer, as Martinez is surely loathe to repeat the constant hamstring injuries the Irishman suffered last season.
The good form of Muhamed Besic in the middle of the park will also play a factor in this decision.
On the other hand, Swansea are currently experiencing a full bill of health for what will be new manager Francesco Guidolin's first game at the helm.
However, even though they have no injuries, there should be little for the Blues to fear should they manage to get rid of the defensive lapses that have cost them throughout the campaign.
