Arsenal vs Man City
Arsenal will assess striker Olivier Giroud's knee injury ahead of the game but midfielder Abou Diaby could be in the squad after playing for the club's under-21 team following three months out with a thigh problem. Defender Andre Santos (stomach muscle) also played in midweek but is not expected to yet feature for the first team, while forward Gervinho is away at the African Nations Cup with Ivory Coast.
City striker Sergio Aguero (hamstring) remains sidelined while midfielder Yaya Toure is at the African Nations Cup along with brother Kolo and back-up striker Abdul Razak. Forward Samir Nasri completes a ban, right-back Maicon (knee) is still out and Micah Richards and Jack Rodwell are long-term casualties - but left-back Aleksandar Kolarov (knee) is in contention.
Man Utd vs Liverpool
Nani and Anderson both return to the United squad - the pair have been sidelined for 14 and eight games respectively with hamstring injuries but are available to bolster Sir Alex Ferguson's options. Wayne Rooney (knee) is missing though and Phil Jones is also likely to be saved for Wednesday's FA Cup replay with West Ham.
Striker Daniel Sturridge, who scored on his first appearance for Liverpool in the FA Cup win at Mansfield, could keep his place. The likes of the rested Steven Gerrard, Jose Reina and Glen Johnson will all return, while forward Fabio Borini is back in the squad having been sidelined since mid-October with a broken foot.
