Ronaldo keen to stay at United

The winger has been in impressive form this season for the Premiership leaders and has begun negotiations on a new improved contract.

He has also been linked with Barcelona and Real Madrid, but United are determined to retain the services of their most valuable player.

Speaking after Portugal’s 4-0 Euro 2008 qualifying win over Belgium on Saturday, Ronaldo insisted he wanted to stay at Old Trafford.

“Am I the best in the world? I have been improving my game and I’m in a great shape this year. I feel mature,” he told the Portuguese media.

“The Manchester United players are by my side and I also have a great help in the national team.

“But of course I believe I am one of the best.

“I have a good contract in financial terms and what really matters to me is to show my game.

“It’s a good sign to know that I have so many clubs interested in me, such as Madrid. It means that I am valued and my work pleases.

“But I’m very happy where I am and I hope to stay in Manchester United for many years.”
