Nicolas Anelka is in contention for tomorrow night's Champions League clash against Genk after traveling with the squad to Belgium.
The former French international striker missed the weekend's 5-3 defeat to Arsenal at Stamford Bridge through injury, but was one of 20 players to depart the club's Cobham training ground this morning.
Portuguese midfielder Raul Meireles is also being tipped to feature against Mario Been's side, with the former Liverpool star making a positive impact off the bench against the Gunners on Saturday.
Didier Drogba will also be in contention for Andre Villas-Boas' side after missing the domestic defeat through suspension, with the Ivorian serving the first of his three-match ban for a straight red card against QPR.
Despite losing at Stamford Bridge a fortnight ago, Been will be hoping his players are full of confidence after an astonishing victory of their own in the Pro League, coming from 4-2 down to beat Club Brugge in a nine-goal thriller at the Jan Breydel Stadium.
Blues target Kevin de Bruyne is again expected to be the key man for Genk, with the teenage Belgian international one of the few to leave west London with much credit following the 5-0 defeat last time out in the competition.
Victory for the Blues would see them move onto 10 points in Group E, and all-but guarantee their place in the first knockout round of the competition with two matches left at this stage.
Second placed Bayer Leverkusen travel to Valencia knowing victory would also guarantee their place in the next phase, with the La Liga outfit knowing nothing less than victory will realistically be enough at the Mestalla Stadium tomorrow night with a trip to the Bridge still to come.
