Rooney has served the three-match ban he received for his sending off against West Ham, but it was claimed earlier this week that the striker had sustained an injury in training, thus potentially delaying his return.
But with this eagerly-awaited game fast approaching, Rooney posted on his official Facebook page to express is excitement and GiveMeSport understands that he is indeed fit to take his place back in Louis van Gaal’s side.
Rooney’s availability will pose something of a selection headache for the Manchester United manager as he still searches for the best way to utilise his strongest players, but the England skipper is expected to slot straight back in.
Van Gaal chose to start Rooney, Robin van Persie and Radamel Falcao during the victory over West Ham in which the former saw red, and it is likely he will do so again when his United side face City.

Either Juan Mata or Adnan Januzaj will miss out should Rooney be included in the starting XI, with Van Gaal having made clear he will use the 29-year-old in a more creative role, rather than as a centre-forward.
United will be optimistic they can add to the recent misery endured by City, who have lost each of their last three fixtures in all competitions, which included a shock Capital One Cup defeat to Newcastle.
City are already six points behind Chelsea in defence of their Premier League title, and United could strike a potentially terminal blow if they inflict a fourth successive loss on Sunday afternoon.
