Born in Rome on New Year’s Day 1999, Scamacca was with the Academies of both Lazio and Roma as a boy before moving to Dutch club PSV Eindhoven at 16 in 2015.
After 18 months in the Netherlands, during which he played three times for Jong PSV in the Dutch second tier, the striker moved home to Italy with Sassuolo. He was still just 18 when he debuted in Serie A away at Napoli in October 2017.
Loan spells with Serie B sides Cremonese and Ascoli and Dutch top-flight club PEC Zwolle followed, before he netted his first Serie A goal while on loan at Genoa in November 2020, and in a local derby with Sampdoria to boot.
After finishing the 2020/21 campaign with 12 goals, including four in the Italian Cup, Scamacca returned to Sassuolo in style last season.
Forging a potent partnership with fellow Italian Domenico Berardi for Alessio Dionisi’s free-scoring side, Scamacca scored a career-high 16 Serie A goals and became a regular in Roberto Mancini’s Italy squad.
After making his debut in a FIFA World Cup qualifying win over Lithuania in September 2021, the forward has earned six further caps, including a start in Italy’s Nations League tie with England at Molineux in June.
Everyone at West Ham United would like to welcome Gianluca to London Stadium and wish him well for his career in Claret and Blue.
