Manchester United boss Sir Alex Ferguson has confirmed Wayne Rooney will be available for tomorrow's derby at Manchester City.

Rooney has been struggling with an ankle problem he aggravated in the second leg of the Champions League clash to Bayern Munich but has trained this week.

If the 24-year-old suffers no reaction he will be in the squad, Ferguson confirmed.

"He has done some work over the last couple of days and we will see how he is for tomorrow's game," said Ferguson, who also confirmed Ryan Giggs and Rio Ferdinand have an outside chance of being involved at Eastlands.
