In an exclusive interview with CNN ahead of this weekend's Champions League final between Bayern Munich and Chelsea, Real Madrid star Cristiano Ronaldo has revealed that he believes he is "better than Messi".

The Portuguese international, who has just finished a highly successful season with his club, winning Spain's Primera Liga a full nine points ahead of arch rivals Barcelona and scoring more goals than he ever has before (46 in the league and 60 overall) says the comparisons with Messi "sometimes make me tired".

"Some people say I'm better," he continued, "other people say it's him, but at the end of the day, they're going to decide who is the best player."

"At the moment ... I think it is me," he laughed.

"You cannot compare a Ferrari with a Porsche because it's a different engine. You cannot compare them. He does the best things for Barcelona, I do the best things for Madrid.

"I think we push each other sometimes in the competition, this is why the competition is so high. This is why Madrid and Barcelona are the best teams in the world because everyone pushes each other, not just me and Messi but other players."

In reference to winning the league title, Ronaldo expressed his immense pleasure, saying: "(It) was my first time, so I was so happy because it's my best moment here in Madrid, the most important trophy. In terms of individual, it was great for me, the goals that I scored, to break my own record ... to do 100 points in the Spanish league which is a record too. It's phenomenal.

"For me this is the most difficult league in the world. To compete with Barcelona, as everyone knows is very complicated and we beat them. Nine points ahead ... so it was an amazing year."
