Former Juventus coach Max Allegri has paid tribute to Mario Mandzukic.
The veteran striker is a target for AC Milan and Manchester United.
Mandzukic has been frozen out by Maurizio Sarri, but Allegri: "He's the example of a special player, he gave me a lot of room for manoeuvre.
"He'd often changed teams, but now he's in his fifth season with Juventus and this is one of my greatest achievements."
