Manchester City are sweating on the fitness of captain Vincent Kompany ahead of Sunday's showdown with Liverpool at Anfield.
The defender hurt his knee in training and City will monitor the Belgium international ahead of the crunch match which could go a long way towards deciding the destination of the Premier League trophy this season.
Joleon Lescott will be on standby to replace Kompany, but City will be desperate to have their skipper available for such a pivotal match.
City's top scorer Sergio Aguero returns to the squad after missing the last five games with a hamstring injury.
Defender Matija Nastasic (knee) is the only notable absentee with midfielder Yaya Toure having overcome a knock suffered in last week's win over Southampton.
The hosts welcome back centre-back Daniel Agger, who missed last weekend's win at West Ham with a knee problem. He is fit again to challenge Mamadou Sakho for his first-team place.
Only long-term injured left-back Jose Enrique remains unavailable for selection to Brendan Rodgers.
Watch Liverpool take on Manchester City at Anfield live on Sky Sports 1 and Sky 3D from 12.30pm this Sunday
