Despite the continuing speculation to the contrary, Cristiano Ronaldo insists that he is happy at Manchester United and "would love to continue" at Old Trafford.

Ronaldo has been alarmingly evasive about his future in England after United's Champions League triumph in Moscow. However, despite reports linking the Portugal winger with Real Madrid, there is a strengthening belief that he will remain in Manchester.

While not denying that it remains "a dream" to play in Spain, Ronaldo reiterated his desire to stay at Old Trafford in an interview with Portuguese newspaper Publico.

"As I have said many times, only God knows the future," he said. "I have never hid from anyone that I would like to play in Spain one day. It's a dream, but sometimes dreams don't happen. I can guarantee that I am happy at Manchester United and that I would love to continue."

"There is nothing certain at the moment. The press always make stories about interest from other teams, not only from Madrid, also from Barcelona. On one hand it's good and means that they know your value as a player and think you can be a good reinforcement for other teams.

"But my head is in Manchester because it is the club that at the moment puts me in the best condition and that I'm happy at."

At the end of his fifth, and most successful, season at the club, Ronaldo insists the credit for his phenomenal performance should go to Sir Alex Ferguson and his assistant Carlos Queiroz.

"He (Ferguson) is spectacular," added Ronaldo. "He is a coach with a lot of experience who has helped me a lot. I've been with him for five years and I barely know him but he is a very experienced coach and always helps me and that's what's important.

"But I have also been supported by Carlos Queiroz, who is also doing some spectacular work. He has helped me a lot and he has a fundamental role. It is him who leads the training sessions, he is there every day with the players and he is an excellent professional. He's a five-star man, as a coach and as a person."
