Torino president Urbano Cairo insists they will not lose Alessandro Rosina.
"I'm keeping a tight grip of him," said the owner. "He knows how to do great things on the field of play as he has shown in the past.
"Despite his fitness troubles last year, he still had a decent campaign. He's now back in shape and he'll soon return to his true levels."
Torino travel to Sampdoria this weekend and Cairo is keen for Rosina to silence those fans who whistled him on Wednesday night.
"Peace will soon break out between the player and the supporters," he added. "I now want Alessandro to concentrate 101 per cent on football.
"If he isn't distracted by other things then he'll soon get back to his best condition."
