West Ham have agreed a £35.5million fee with Sassuolo for Italy striker Gianluca Scamacca.
Talks are ongoing as Sassuolo also want a percentage sell-on inserted into the deal which is £30.5m plus £5m in add-ons, and personal terms have still to be agreed.
The 23-year-old Scamacca, who has five caps for the Italian national side, scored 16 goals in 36 Serie A appearances last season as Sassuolo finished 11th in the league.
