United, who accepted Real’s offer for the winger on June 11, have confirmed the move has been finalised and he will be presented to the fans on Monday.

The £80m fee for the 24-year-old has been paid in full.

“Everyone here wishes him well in his future career,” United manager Sir Alex Ferguson told the club’s website.

A statement on Real’s website read: “The player will be tied to Real Madrid for the next six seasons. He will be presented on July 6 at the Santiago Bernabeu.”

Ferguson paid tribute to a player whose goals have played a large part in bringing three successive titles to Old Trafford.

“Cristiano has been a marvellous player for Manchester United,” he said. “His six years at Old Trafford have seen him develop into the best footballer in the world.”

“His contribution has been a major factor in the club’s success in that time and his talent, his ability to entertain and his infectious personality have enthralled fans the world over.”

Ronaldo was on holiday in the United States at the time the offer was made by Real on June 10.

During that time, United stated that the decision came at the Portugal international’s request after he “again expressed his desire to leave”.

The addition of Ronaldo to the Real ranks is part of a remarkable spending spree by the Spanish giants since Florentino Perez returned as club president on June 1.

He brought in Brazil playmaker Kaka for a then world record £56m, Ronaldo was then lined up for £80m before centre-back Raul Albiol was signed from Valencia for £12m, to bring Real’s total summer spend, so far, to £148m.

Perez appointed Villarreal boss Manuel Pellegrini as Real’s new coach and had previously made it clear he would do “everything possible” to sign Ronaldo.

Reports have suggested that the midfielder will earn about £11m per year, which will make him the highest paid footballer in the world. He was on about £6.38m at Old Trafford.
