Owen Hargreaves could return to the Manchester United bench after 19 months out with a knee injury, while John O'Shea could also return. Wayne Rooney, injured in midweek, will be replaced by Dimitar Berbatov. Chelsea manager Carlo Ancelotti will recall Didier Drogba, who has recovered from a knock that prevented him from training earlier this week. Drogba's return could mean Joe Cole drops to the bench, with Nicolas Anelka taking up a deeper role. Man Utd Injured: Anderson (knee), Brown & Welbeck (both metatarsal), Owen (hamstring), Rooney (ankle) Chelsea Injured: Bosingwa, Essien & Ivanovic (all knee), Carvalho & A Cole (both ankle)
