Manchester City's faint hopes of retaining their English football title will hinge on their match at Manchester United this morning.
City's manager Roberto Mancini has already conceded that their defence is over and a loss today would drop them 18 points behind their rivals with 7 matches remaining.
Wayne Rooney is expected to return for United after missing their last couple of matches with a groin injury.
City won 6-1 in last season's corresonding fixture in what was United's heaviest Premier League defeat and the first time they had conceded six at Old Trafford since 1930.
This is the 165th Manchester derby in all competitions. Manchester United lead by 69 wins to City's 45, with 50 draws.
The match starts at 7.
