AC Milan captain Leonardo Bonucci says they need to start shopping at the top end of the market.
Bonucci wants to see management buy big this summer.
The defender - a €40m arrival from Juventus last year - told Calciomercato.com: “Mirabelli and Fassone don't need advice.
“If I had to give them some, I'd tell them to buy top international players.
"By doing so, the level in training also rises. It's crucial."
