Inter supporters have repeatedly jeered the striker and even tried to attack him in the San Siro car park after he threw his shirt to the ground in the first-leg of their Champions League victory over Barcelona.
Agent Mino Raiola revealed: "A few days ago Mario found that someone had loosened the wheel nuts on his car. If someone isn’t careful, he risks getting killed on the motorway.
“We certainly cannot carry on like this. In these circumstances Mario will not remain for another year at Inter, I can guarantee that.”
Balotelli made a public apology to the Nerazzurri, but the tension surrounding him remains sky high.
“Mario is not angry with the fans, nor with his teammates, but clearly the problems with the club have not been resolved,” continued Raiola.
“I don’t know if and how quickly they can be resolved. Balotelli apologised sincerely, but someone at the club didn’t understand that. They didn’t want to understand it.
“Now I think I really need to talk to the club. I have to defend the interests of my client. I discuss matters with the club, then I don’t know if the club is led by Mourinho or not. It depends on President Massimo Moratti.”
