Thiago Silva remains hopeful of Paulo Henrique Ganso joining him at AC Milan.
The Santos star is wanted at the Rossoneri.
Thiago Silva said: "Zlatan Ibrahimovic has brought a winning mentality to the side. Right from the first game he told us we always had to win everything, so if we do get the Scudetto it will be primarily down to him.
"I don't think Alexandre Pato is missing anything to be considered a phenomenon, as he is the complete striker. He has even learned how to defend.
"I spoke to Ganso a couple of days ago and confirmed he should join us, but he knows perfectly well it's the best choice. Ganso and Neymar are the best Brazilians around right now.
"Kaka is fast and explosive, whereas Ganso is better at keeping hold of the ball. He can become the new Zinedine Zidane."
