Reading boss Brian McDermott has an almost fully-fit squad to choose from, with just two notable absences. Goalkeeper Alex McCarthy (shoulder) is out, so Adam Federici will continue to deputise.
At the other end of the pitch, Jason Roberts (hip) remains sidelined, so Pavel Pogrebnyak is expected to start up front – the Russian striker was rested for the Royals' 4-0 FA Cup win over Sheffield United.
Chelsea are without Eden Hazard, who is serving a suspension for kicking a ballboy in the Capital One Cup; in the Belgian’s absence, Ryan Bertrand could be handed a starting berth on the left wing ahead of Marko Marin.
Nigerian duo Victor Moses and John Obi Mikel are both on Africa Cup of Nations duty, so remain unavailable for selection, while Oriol Romeu (knee) is the only long-term absentee.
John Terry started in the FA Cup against Brentford but is likely to return to the bench against Reading. David Luiz will not play, while Fernando Torres should keep his place up front after netting against the Bees.
Ross Turnbull is set to continue in goal following his appearance against Brentford, with Petr Cech (calf) still unavailable.
