Real Madrid "would be stupid" to sell Cristiano Ronaldo during the next transfer window, claims Spanish expert Guillem Balague.

Balague argued with his colleague, Terry Gibson, and insisted Los Blancos should hold onto to Ronaldo for another year.
"Real Madrid should not sell him this summer as he is still in a condition where he can actually make a difference to the team," he told Sky Sports.
"If he goes to Manchester United or Manchester City, he will make a difference, he will still be scoring and you could still get a lot out of him. So it would be stupid to get rid of him.
"And while there may also be a football argument to get rid of him, there is certainly no financial argument to do it. For Madrid he is still the key to their business model on and off the pitch, especially off the pitch."
Balague insisted that Ronaldo will stay another season at Bernabeu, but could move on in 2016.
"They gave him a new deal recently and the idea is to keep him for the summer," Balague added.
"Now next summer is when I think we will start hearing a lot of stories about Ronaldo where not only Madrid, but Ronaldo, may think about leaving.
"Now this is in a year and a half's time when he will be 31, so an age when he can still do a lot for Madrid, but from that summer on we are just going to hear a lot of stories about clubs trying to convince him to move on.
"This summer he is certainly going to stay. Next summer is going to be fun."
