The Rosanero host Juve on Saturday.
"Juve have no world class players,” said the forward during a press conference.
“I thought Mirko Vucinic would be able to do more, but he had a few problems. Unfortunately for us, he is now getting back in shape.
“I respect Marco Borriello and Alessandro Matri, but they are not Zlatan Ibrahimovic. However, Andrea Pirlo is having a great season and I hope he gets a few passes wrong on Saturday.”
