Former Inter Milan striker Antonio Cassano says they must keep hold of Ivan Perisic.
Off contract in June, the veteran attacker is in talks with Chelsea.
Cassano said: “He's had a sensational season, but has (general manager Beppe) Marotta noticed?
"If he leaves Inter are shooting themselves in the foot, he's had the best season of his career, the club must give him a three-year contract."
Perisic has already slammed Inter after their previous contract offer.
Cassano added: “It's normal to say things like that there."
