City will have to maintain their title challenge without the services of midfield driving force Yaya Toure as a heads for the Africa Cup of Nations.
But defender Pablo Zabaleta has urged all his team-mates to step up to compensate for the loss of the Ivory Coast star, his brother Kolo and back-up striker Abdul Razak.
The Argentina international said: "It's going to be a very tough time for us because we're going to lose Kolo, Yaya and Abdul, three important players.
"Yaya has been a regular player for a long time. We know how important Yaya is to the team but there are other players who can do the same job.
"Everybody is important for the team and we need to keep working hard.
"Last season, January and February was when we dropped points and we need to try to make sure that doesn't happen again."
