Carlos Tevez says he will not play for Manchester United next season and has accused the club of showing him a lack of respect.
The striker's future has become a hot topic, with United fans urging the club to keep the Argentinian following the end of his two-year loan spell this summer.
But a deal has so far not been agreed, with Tevez also unhappy at the amount of time he has spent on the bench this season.
The 25-year-old told Argentinian TV station TYC: "I know that I am not going to continue at Manchester United.
"I feel that they have lacked respect towards me. It's not about whether they pay £5million more or £5million less, but I feel I have been badly treated.
"There are ways in which the club is managed that I don't understand. When you don't agree with the manager in how the club is run... I don't have faith in a lot of things that happen here.
"I've been here for two years and the directors have never come to speak to me. Not once have I had a meeting with them.
"Therefore, it's best that I leave the club so as not to clash with (manager) Alex Ferguson and the directors. Neither do I understand why I don't play in the team.
"I've asked (adviser) Kia (Joorabchian) not to speak to me about offers during the next 10 days. I want to concentrate only on the final matches that we have to play.
"Afterwards, I've got a month to take a decision and choose where to go."
Tevez was tearful as he waved to the fans after Saturday's 0-0 draw with Arsenal, which sealed United's third successive Premier League triumph.
"It's emotional," he said. "I like Manchester and I like the fans. But maybe it is goodbye. It is very difficult."
Manchester United chief executive David Gill said of the comments: "I haven't seen them, I haven't read them. I don't think it's right to do these negotiations through the press.
"If he's said that I think it's borne out of frustration but he's got to understand, and I'm sure his advisers understand, these are big decisions to be taken, large amounts of money, and I think the timeline isn't quite as quick as some people would want it to be.
"If I speak to him in the dressing room or at the training ground he's always very personable and friendly and I think that's what we have at the club."
