John Terry looks set to lead Chelsea out in the London derby against the Gunners.
Manager Andre Villas-Boas had no concerns about Terry's state of mind for the clash in the midst of the racism inquiry faced by his captain.
Ramires is fit to return following a knee injury, Fernando Torres is set to start a domestic match for the first time in more than a month following his three-game ban, Didier Drogba is still suspended, as is Ross Turnbull, while Hilario has flu.
Centre-back Thomas Vermaelen is expected to be available for Arsenal's trip to London rivals Chelsea.
The Belgian defender limped out of the midweek Carling Cup win over Bolton on what was his return from an ankle injury, but that proved to be nothing more than cramp in his calf.
Full-back Carl Jenkinson (knee) faces a late fitness test, but Kieran Gibbs (stomach) remains out, along with midfielders Abou Diaby and Jack Wilshere and full-back Bacary Sagna (all ankle).
