Chelsea's summer signing Diego Costa is ready to start for the Blues at Old Trafford despite his hamstring issues and remaining overnight in a hospital during the week with a virus.
Jose Mourinho has been drenching on his striker's fitness but sources say Costa came through training yesterday and he's ready to be selected.
Mourinho already said the Premier League’s leading goalscorer [Diego Costa] needed to train with the squad and if there are no signs of illness, he would be starting at Manchester today.
My understanding is that the Brazilian born striker has done enough to convince Jose he is ready for the tie.
However, Costa starting for the Blues comes as a major uplift to Chelsea, as they go into the clash today without Loic Remy - who picked up an injury in their midweek Champions League match against Maribor - and would have depended on Didier Drogba to lead the line.
The Red Devils boss Louis van Gaal has his own selection problems as United captain Wayne Rooney completes his ban and Radamel Falcao is also a doubt due to a heavy knock he got in training on Friday.
Robin van Persie has scored only two times in eight Premier League appearances this season.
Another concern for Van Gaal is Angel Di Maria who was taken off at West Brom on Monday night because of a thigh strain but sources say the Argentina winger is fit to start.
Ramires could also return after being sidelined for a month.
Predicted starting line up for both teams.
Manchester United: De Gea, Rafael, Jones, Rojo, Shaw, Herrera, Blind, Di Maria, Valencia, Mata, Robin van Persie.
Chelsea: Courtois, Ivanovic, Cahill, Terry, Felipe Luis, Matic, Fabregas, Oscar, Hazard, Willian, Costa.
