The agent claims that Jo has five offers to consider from interested clubs in the January transfer window.
Jo has recently been linked with a move to Greek giants Olympiakos.
“There is no option for Jo to go to Greece,” Guliano Bertolucci told Greek website Sday.
“He has played in most of the last few games at City and doesn’t want to leave on loan.
“Jo has five offers right now from clubs outside of England but he doesn’t want to leave.
“There is no offer from Olympiakos. We have offers from Spain, France and Russia.”
