Manchester City have to shrug off the body blow of letting a two-goal lead and the chance to win the Premier League title against bitter rivals Manchester United slip to raise themselves for a Champions League rescue mission against Liverpool on Tuesday. Victory against United would have seen City crowned champions of England for the fifth time, and they looked well on course to do so in the sweetest style in Saturday's Manchester derby as captain Vincent Kompany and Ilkay Gundogan propelled them into a richly deserved two-goal half-time lead. However, City's chances of landing a first ever Champions League crown were likely dealt a fatal blow when they conceded three times in 19 minutes first-half minutes to a rampant Liverpool at Anfield in the first leg last week.
