Carlos Tevez's advisor, Kia Jorabchian, expects him to leave Manchester United and sign for cross-town rivals Manchester City.
The Argentine's contract expires at the end of this season and it looks almost certain that he will move on from Old Trafford.
Joorabchian believes Tevez is looking for a new challenge.
"He feels there is a very big chance that his time has come to an end and it is time to move on," Joorabchian told Sky Sports News.
"He loved his time there, he mentioned that, and the glory he has had there has been very special to him.
"But the fact that they have not offered him a contract or made any effort to sign him up means that he probably has to move on and think about his own future."
