The Uruguayan will become a free agent at season's end.
Asked who his former club should sign in the summer, the Dutchman told SPORTbible: "Edinson Cavani. I would definitely go for Cavani; he's very fit, he's a proven goalscorer, a goal machine, he has proven it at Napoli, PSG and Uruguay.
"With him, if he starts, he will get you 25 goals a season. I've watched him play, I've played against him, he is like a proper goalscorer. He lives by scoring goals so I'd go for him."
