Real Madrid coach Carlo Ancelotti is "certain" Cristiano Ronaldo will quash speculation over the possibility returning

to Manchester United by signing a contract extension at the Bernabeu.

Ronaldo, 28, is contracted with Madrid until June 2015 but has been linked with a move back to Old Trafford either this season or next.

Los Blancos have remained adamant that they will keep hold of the Portuguese winger despite therumours, but doubts were raised on Sunday when Ronaldo said "the situation still hasn't been resolved and I don't think now is the right time to talk about it".

Speaking at a press conference in Miami ahead of Madrid’s International Champions Cup final against Chelsea, Ancelotti seemed confident Ronaldo's desire is to stay in Spain.

"The player wants to renew his contract and the club want him to renew it too, so I don't think it's going to be a problem," he was quoted as saying by Madrid-based newspaper AS.

"I think Cristiano and the club are

relaxed about the issue. I don't know when it will happen, but I am certain that Cristiano is going to renew his contract with Madrid."

Ancelotti refused to comment further on Madrid's links with Gareth Bale after angering Tottenham boss Andre Villas-Boas last week by declaring the Spanish side are “negotiating" to sign the Welsh winger.

"I won't speak about Bale, because I have already angered him (Villas-Boas) and 1 don't want to anger another coach," Ancelotti added. "I didn't say anything in particular and I prefer not to talk about this. ”
