Real Madrid winger Cristiano Ronaldo has heaped praise on former Manchester United teammate Wayne Rooney over his form this season.

Rooney netted twice in Manchester United's 3-2 Champions League first leg win at AC Milan and will play tonight after recovering from a knee injury.

Ronaldo said of Rooney: "He is sensational at the moment.

"If he carries on like this he will soon be very close to the number of goals I scored."
