Speculation continues to linger over where Tevez will be playing his football next season as he nears the end of a two-year loan deal at Old Trafford.
United are thought to have an agreement in place to pay around £30million to an investment group that handles Tevez's affairs, but as yet they have failed to rubber-stamp this arrangement.
The Argentine does not know what the future will hold, telling the Daily Express: "I do have a great feeling about Manchester United and, in particular, the fans. I have a great affection for them and they have made the feeling phenomenal.
Not sure"But at this point I am not sure if I will stay, not least because it is not just my decision.
"It is up to Manchester to decide if they want to keep me - and I have to decide what is right for my career, for my future."
Tevez impressed in his first season but has found his opportunities limited since the summer arrival of Dimitar Berbatov.
This situation continues to frustrate the striker, who said: "This season I have been benched and I find that hard to understand when I am not playing badly."
Tevez's uncertainty over his future comes after skysports.com learnt that reports linking him with a move away from Old Trafford are some way wide of the mark.
A national newspaper quoted Tevez's advisor, Kia Joorabchian, as saying the player is effectively 'in the market' and that United no longer have an 'option' to secure the Argentine's services in the summer.
CommittedHowever, Joorabchian insists that Tevez is still very much committed to remaining in Manchester and that talks are ongoing between all parties.
Meanwhile, the striker also questioned why the on-going 'Carlos Tevez affair' should be called that, saying it has nothing to do with him.
"As far as I am concerned, why should it be the Carlos Tevez affair? It is West Ham's affair. This is not my problem and it was not my fault. I did nothing wrong," he said.
He added: "If West Ham have not submitted the documents correctly, that is down to them."
