City boss Roberto Mancini has revealed his interest in the striker, who is currently on loan at AC Milan from Barcelona.
“Mancini has paid a great compliment to Zlatan by saying he might make the final leap to Manchester City,” Raiola told Radio Radio.
“But he must not speak with me but with (Milan chief Adriano) Galliani and it won’t be easy to take him away.
“Mancini knows what it means to have Ibra in a squad but I think it’s impossible that Milan will sell him.
“When Zlatan went to AC Milan I said they were getting not just a player but also a winning mentality.
“Ibrahimovic doesn’t like to lose and he has brought that mentality to AC Milan.
“In football everything has a price, but Ibra is not going to go away. He wants to grow with Milan. They will have a team to compete in Europe.”
