Gianfanco Zola says AC Milan should've fought harder to keep Sandro Tonali.
The midfielder is joining Newcastle United in an 80m deal.
Zola is surprised Milan cave so easily when Newcastle made their offer.
The ex-Chelsea striker told La Gazzetta dello Sport: Milan are a fantastic team, to me they'll always be among the best in the world.
"Of course, the player's will may have counted, it's hard to reject certain offers, but if I were Milan, I would have tried to keep him."
