"He is one of the 10 best strikers in the world, and the number one in Italy", he told RAI about the 33-time capped Italy global.
A story from 2009, when Balotelli was playing under Mourinho at Inter Milan, has been told over and over again in relation to the Italian's hard personality.
"I said to him: "Mario, I can not change you, I have no strikers on the bench, so don't touch anybody and play only with the ball".
Say what you want about the controversial super-agent Mino Raiola, but he really does work hard for his players.
Italy worldwide Balotelli came through the ranks at Inter as a teenager and looked destined to become one of the world's elite players.
"Mario is ready to come back to Italy".
Raiola said that he is now in talks with teams from England and Italy about securing a move for the 27-year-old but seemed to rule out a return to AC Milan where Balotelli scored 30 goals in 54 games between 2012 and 2014.
Raiola also claims there is interest from Premier League clubs; Balotelli has also played for Manchester City and Liverpool in a career full of surprise moves. He's worth €100 million, but he's available on a free, so he's a bargain.
He has to go to a top club next year, I've already said that.
