Former Real Madrid defender Ivan Campo can see Cristiano Ronaldo returning to Manchester United.

Jose Mourinho's appointment at Old Trafford has seen Ronaldo linked with a move back to the club that signed him aged 17 from Sporting Lisbon over a decade ago.

“Anything can happen in football if the money is right so Ronaldo could well go back to Manchester United," he told 888Sport. “Money talks!"

Campo added: “Of course there is going to be speculation after last summer, but we will have to wait and see if this is the year that he finally makes the switch.

“In Spain we have had great goalkeepers like Iker Casillas and now we have De Gea," he said.

“He can be the best keeper in the world if he's not already."
