Carlos Tevez has admitted he may leave Manchester United if he gets a suitable offer from another club.

The Argentinian forward has become frustrated at the lack of progress over talks to turn his loan deal at Old Trafford into a permanent contract. The Argentinian also risked the ire of United boss Sir Alex Ferguson by saying he would like to play for Real Madrid.

Tevez joined the club on loan from West Ham in 2007 and has become frustrated at waiting for that temporary deal, which runs out next summer, to become a long-term arrangement.

“Now all clubs are on an equal footing. If a club comes to me and offers me a five-year deal, I will accept it for peace of mind,” the 24-year-old told a radio station in his homeland.

“I will sign my last contract, and then I figure that I’ll go back to Boca [Juniors]. That could be in four or five years. I want everybody to know no offer has been made. I don’t like that they are playing with our fans, who show their love to me in each match.”

The Argentinian also indicated that he would like to play for Real Madrid – an admission that will annoy Ferguson in the wake of the Spanish club’s highly publicised pursuit of United winger Cristiano Ronaldo.

“Who wouldn’t want to play for Real Madrid,” he said. “Like Manchester, they are one of the best clubs in the world and it would be a pleasure to play for them.”

Tevez said that if he leaves United he wants to “quit on good terms” but admitted he is unhappy with Ferguson for comments the manager made regarding his contract.

“I didn’t like him [Ferguson] saying I didn’t like the offer I was made because neither my agent nor me were given one,” he said. “I don’t know anything on my future. United know what they must pay if they want me to stay. I want to stay but the club have not made any offer. I’ve been waiting for them for a year and a half.”

There is an agreement in place with Tevez’s agent, Kia Joorabchian, for United to secure Tevez for £32m but the Premier League champions may be reluctant to pay that price.
