Former Italy midfielder Massimo Ambrosini has warned Juventus over new contract talks with Paulo Dybala.

Dybala and Juve are locked in talks about a new deal.

Ambrosini said: "Juve have stakes like Milan had when they had to choose whether or not to renew (Gigio) Donnarumma.

"The reference to attachment makes you say 'we'll get to here, if you're okay with it, okay ...'. It's complicated though.

"You make the Juventus fans understand that you are on a horizon of cost sustainability: however, the world must change, Milan has given up the strongest goalkeeper in the world."
