Manchester City boss Roberto Mancini has revealed he doesn't intend to sell Jo in January.
The Brazilian striker was expected to be offloaded in the winter market.
But Mancini says: "Jo is a good player, he can help us this season and he is a good man who works hard.
"He is a striker and sometimes you need a player who can go in the box near Carlos Tevez to ease pressure on him. He can also help us defend, and he did that very well at Fulham."
