Alen, you are old enough to have seen Del Piero be transferred to Manchester United every 3 years before he got a new contract.
And like, a million players between then and now.
Bonucci gets interest, so his agent is gonna listen to it and tell juve "player wants to stay but wants to feel him beeing important to juve, aka get a big raise", so he'll get a big raise and thats it.
