Carlos Tevez has revealed he is ready to quit Manchester United if the club continue to stall over signing him on a permanent basis.

The Argentinian, 24, has been on an extended loan at Old Trafford since moving from West Ham United in August 2007 but his deal expires in the summer and although he would love to sign permanently with the Premier League champions, he has given the first indication that he is becoming increasingly frustrated by the lack of progress.

Tevez has been somewhat irritated by Sir Alex Ferguson, the United manager, intimating that he had already rejected an offer from the club

“I want everybody to know no offer has been made," Tevez, who has been given a week off by United, told Radio del Plata in his homeland. "I don’t like that they [United] are playing with our fans, who show their love to me in each match.

“I want to stay but the club have not made any offer. I’ve been waiting for them for a year and a half.

“If I have to quit the club, I want to quit on good terms. 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.

“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.”

Tevez yesterday revealed his disappointment at speculation that he had rejected a new offer from United and today he reiterated his desire for his future to be sorted out.

“I didn’t like him [Sir Alex Ferguson, the United manager] 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."

Tevez's economic rights are owned by an investment fund headed by Kia Joorabchian, who insists Tevez is keen to stay at Old Trafford.

"Manchester United have indicated they would like to sign Carlos for the long term, but we have not started negotiations yet," Joorabchian said. "Carlos has always said his intent is to stay at United and nothing has changed.

"The supporters have been amazing to him and he loves the club."

United's problem, though, is that because the player has failed to regularly hit his really best form, he is therefore hardly looking a snip at the reported £32 million fee he is likely to cost. Real Madrid, the Spanish champions, are monitoring the situation closely.
