Carlos Bacca’s agent is expected to meet West Ham United next week after Milan received a formal €30m offer.
The Colombian striker arrived in Serie A only a year ago from Sevilla for the same transfer fee.
He was their top scorer this season, but does not fit into new Coach Vincenzo Montella’s plans.
Bacca will be sold to help raise cash for other transfers ahead of the Chinese takeover of the club, which is expected on July 15.
According to Sky Sport Italia pundit Gianluca Di Marzio, West Ham made a formal offer worth €30m on Friday.
The Rossoneri accepted and opened the door for Bacca’s agent to speak with Hammers directors early next week.
