Chelsea could welcome back Michael Ballack, Deco and Didier Drogba for their UEFA Champions League clash in Porto.
The trio all sat out of the Blues' 4-0 win over Wolves at the weekend with respective knocks but Carlo Ancelotti is still without Frank Lampard and Jose Boswinga.
Ricardo Carvalho could also come back in against his former club having been rested on Saturday.
Man of the moment Gael Kakuta could also feature after impressing off the bench against Wolves and he has been included in the 20-man squad.
Chelsea have already qualified from Group D alongside Porto but a win at the Estadio do Dragao for the Blues would guarantee them top spot.
