Manchester United winger Cristiano Ronaldo insists he was misquoted when he said Chelsea duo Michael Ballack and Andrei Shevchenko had not improved the Blues.
Reports on Friday suggested the Portuguese star had been critical of the defending Premiership champions in the build-up to Sunday's Old Trafford clash between the top two.
However, Ronaldo told MUTV: "I didn't do an interview and I didn't say the things I have seen written.
"I respect Chelsea and everybody in their team. But I have my own ambitions for my own team and I hope to win on Sunday.
"I am enjoying myself a great deal. The team are playing well, which helps. I feel I am learning and improving every year.
"I am becoming more mature and more consistent. I understand what it means to play for Manchester United a lot more. I feel great and I want to keep it going."
Ronaldo had been quoted in Zoo magazine as saying: "I think we're capable of winning everything - the Premier League, FA Cup and Champions League.
"This weekend's game with Chelsea is very vital. We're neck-and-neck with them and this is a good sign, because we can't allow them to go too far ahead like last year. We're in a better position to win the league.
"I think Chelsea are about the same as they were last year. The transfers of Shevchenko and Ballack haven't changed them too much in terms of their superiority to everybody else. They have to work harder to win games. They just do enough to win."
