Fiorentina midfielder David Pizarro has had a pop at former AS Roma teammate Daniele de Rossi.

De Rossi is at odds with Roma coach Zdenek Zeman after his axing for victory over Atalanta.

"I always support Roma from afar," Pizarro told Radio Mana Mana. "If a team of mine were to win against them, I could not cheer.

"De Rossi is not in charge at Roma. He should try and clarify his position with Zeman. I think it would be good for everyone if he clarified."
