Manchester City boss Roberto Mancini expects his players to learn the lessons from their shock loss at Sunderland very quickly.

City squandered the chance to open up a three-point lead at the top of the Barclays Premier League as they conceded at injury-time goal at the Stadium of Light. The defeat compounded the frustration felt after a goalless draw at West Brom on Boxing Day and there is little time to dwell as Liverpool visit the Etihad Stadium on Tuesday.

Mancini said: "I thought we threw three important points out of the window. It was important but now it is finished and we can do nothing. But at the same time, when we arrive back in Manchester, we need to think positively for the next game and for the future."
