Chelsea have no fresh injury problems for Wednesday's Premier League trip to Arsenal .
Defender David Luiz (knee) and forward Charly Musonda (groin) remain out.
Both have returned to training and could feature in Saturday's FA Cup trip to Norwich.
Arsenal pair Mesut Ozil and Laurent Koscielny have a chance of returning for the Gunners.
Arsene Wenger said that Koscielny had a 30 per cent chance of playing against the champions, while Ozil is closer to a return and his knee injury will be assessed before the match.
But they will have to make do without full-back Sead Kolasinac after he took a knock to his ankle in the draw with West Brom at the weekend.
Aaron Ramsey and Olivier Giroud are both still recovering from hamstring problems, while Nacho Monreal is again out with an ankle injury.
