DM) John Obi Mikel
With Nemanja Matic likely to be rested, Mikel should continue at the heart of the midfield.
DM) Ramires
With the arrival of Nemanja Matic Ramires has seen his first team chances reduced, but should get a run out against Sporting.
CAM) Andre Schurrle
The German has been criticised for his defensive work-rate, but is likely to be given some freedom playing behind Diego Costa.
