According to The Guardian, the Hammers have struck a deal to bring the 23-year-old striker to London after positive talks with the Serie A side.
However, both clubs still remain in talks as Sassuolo also want a percentage sell-on inserted into the deal which is £30.5m plus £5m in add-ons. Also, personal terms between the player and the East London side have still to be agreed upon.
David Moyes’ side want an extra striker to provide cover for Michail Antonio and have identified Scamacca as the ideal candidate for the job after his impressive showing for Sassuolo last season. The Italian who has five caps for the national side scored 16 goals in 36 Serie A appearances last season as Sassuolo finished 11th in the league.
The Hammers are also in the hunt for Chelsea striker Armando Broja but are being put off by the Blues’ valuation of the player. However, they are continuing to wait on Chelsea to see whether they will reduce the asking price for the Albanian.
Meanwhile, they have also made a £12m offer for Eintracht Frankfurt left-winger Filip Kostic. The 29-year-old impressed against The Hammers in the Europa League last season, and his agent Alessandro Lucci is also the agent of Scamacca.
