Soccer:Cristiano Ronaldo is "very happy" at Manchester United. The Manchester United winger has been back in the headlines again over the past 48 hours, thanks to more speculation linking him with Real Madrid.

But comments from Real director Pedro Trapote have been greeted with disdain at Old Trafford, Alex Ferguson claiming "I wouldn't sell them a virus" following his team's 5-3 Club World Cup victory over Gamba Osaka.

Ronaldo opted not to get embroiled in the war of words between two clubs, who may get drawn together in the Champions League knockout round on Friday.

However, he has confirmed he remains happy with life at Old Trafford - after Ferguson persuaded him to stay last summer.

"I don't care what people are saying," he said. "I have not read it. I am here in Japan and I know nothing about what is going on around me.

"But I am very happy playing for Manchester United."

After the intense speculation that surrounded him last summer, it seems Ronaldo must once again get used to being the centre of attention.

The Ballon D'Or winner preferred to talk about his goalscoring contribution to United's latest triumph.

After heading home a Ryan Giggs corner in first-half stoppage time, Ronaldo has moved into double figures for the season.

As he prepares to be confirmed as the best player in the world at a glitzy Fifa ceremony next month, Ronaldo confirmed life at the moment is going well.

"It would mean a lot for me to be a world champion," he said.

"It would be fantastic to win this trophy - and now there is a good chance, not just from a personal perspective but for Manchester United.

"We might only have one opportunity and we have to take it."

Ronaldo knows the bare minimum about Sunday's opponents, Ecuador's South American club champions LDU Quito.

They were not that impressive in beating Pachuca in Wednesday's semi-final, but Ronaldo knows any club capable of overcoming the might of Brazil and Argentina must be respected.

"We are expecting a difficult game," he said.

"The second match is always more difficult than the first, and we have to prepare well.

"Quito are a good team, with a lot of experience.

"We have a couple of days to study them and to see who the best players are, but the most important thing for us is to put the ball in the net."
