Arrigo Sacchi, coach of AC Milan during the golden era of the late 80's, has urged the club to not sell Kaka. Speaking to Radio Rai, Sacchi was adamant that Kaka would be difficult to replace even with multiple signings funded by the Brazilian's transfer fee.

"If Milan were to sell Kaka and then to spend the same sum on three or four players, they would be making a mistake in my opinion," Sacchi said.

"Kaka is unique. He isn't just a great talent, but a professional who lives for football.

"He is a positive example in the way he plays and the way he lives his life."
