"This season has been a great one for me - I've scored a lot of goals, the team have played very well and we're champions. It's amazing."
Ronaldo, who was inspirational in United's road to the Premier League title, spoke of his delight at winning the league.
"It's a great feeling to win the league - I don't have the words to describe how it feels to be champions, it's amazing," added Ronaldo. "I didn't think it would go to the final day of the season, but to be honest the feeling is better [to win on the last day].
"When the ref blew the final whistle it was brilliant. We've worked hard for nine months and I feel very proud to be champions."
