Calderon: Ronaldo could leave Real Madrid next summer

The man who took Cristiano Ronaldo to Real Madrid in 2009 thinks it's possible the Portuguese star could leave the club next summer.

Los Blancos play Paris Saint-Germain in the Champions League on Wednesday night and the French club are regularly linked with a move for Ronaldo.

Ramon Calderon says he'd like to see the 30-year-old stay in Madrid, but admits he may decide to leave when the season finishes.

"I have heard rumours that there's strong PSG interest [in Ronaldo]," he told Le Parisien.

"As the former president of Real Madrid, I hope that it never happens. But as someone who knows football, I think it could be possible.

"For now, Cristiano hasn't expressed [a desire to leave]. I think he will take a decision at the end of the season, depending on the titles won and the feelings he has.

"In the meantime, the mystery will continue."

Calderon added that the "cold relationship" Ronaldo has with current president Florentino Perez could prove a factor in a possible departure.

He also doesn't imagine the likes of PSG or Manchester United will be put off by a €100 million price tag.

"Cristiano Ronaldo is priceless because of what he gives to the team," the 64-year-old continued.

"In terms of goals and mentality, there is no equivalent [to Ronaldo], except [Lionel] Messi.

"If PSG or Manchester United buy Ronaldo they’ll have no problem paying off the price - he will raise it himself thanks to marketing revenue."
