With Real Madrid renewing their interest in the Portuguese superstar, he declared: "I am at the ideal club to grow and to reach the summit. That's the key to my success.
"When I came to England, I was only 18. In four years, everything has changed.
"I have become more sure of myself and thus I now have great ambitions for my club and for myself this season.
"With my team-mates, the understanding is remarkable. Nani, he's a good mate. Like me, he came from Sporting Lisbon. He's a very gifted player but he and I are not alike really.
"He has his own personality, his own style. He is only 21 and has much to learn. And, like me, he has chosen the ideal club to progress with and to lead a solid career.
"With Wayne Rooney, everything's going well. Despite what happened between us in the past there are no problems or worries now."
Although Ronaldo could not resist a little jibe at his friend and team-mate's expense.
He said: "He won't be at Euro 2008. I will be, though! I really want to win that. I will do everything to take us all the way."
