Manchester City player Aleksandar Kolarov believes it could take 12 wins from their next 12 games in order to secure the Premier League title.
The Citizens have fallen down to fourth in the Premier League after not being involved in league action due to their postponed game against Sunderland and their Capital One Cup against the Wearside outfit. City beat the Black Cats 3-1 at Wembley to win their first League Cup in 38 years.
The club are six points off leaders Chelsea who sit top of the league on 63 points, but with two games in hand over their rivals the title is still in their own hands. Chelsea however, could stretch their lead over Kolarov's side to nine points this weekend with Mourinho's team playing Tottenham Hotspur at Stamford Bridge, and City again being out of action in the league.
They are involved in a repeat of last years FA Cup final in their quarter-final match against Wigan Athletic on Sunday, and Kolarov admits it is a test of nerve in the title race, and the team who holds theirs the best will emerge victorious.
"It will be very difficult to the very end because now we have played two games less than Chelsea and we need to win them, it's very important we do that because we want to keep things in our own hands."
"We have 12 more games to play and every single one of them is going to be tough. This is the important stage of the season and we have to hold our nerve.
"It is the team that handles the pressure better that will win.
"It's massive for us, we might need to beat every single team we play between now and the end of the season to win the Premier League."
Manchester City's next Premier League game isn't until the 15th March when they come up against former Manchester United player Steve Bruce as he aims to prevent the Blues from achieving a league double over his side, after Pellegrini's men beat them 2-0 at the Ethiad in August.
