WEST HAM signed Italy defender Emerson Palmieri from Chelsea in a deal worth a reported £15 million (€17.8 million) on Tuesday.
Emerson has agreed a four-year contract with the Hammers, with the option of a further one-year extension.
The 28-year-old left-back was born in Brazil, but moved to Italy in 2014 and was eventually granted citizenship.
He struggled to break into the Chelsea team in five years at Stamford Bridge and spent last season on loan at Lyon.
Emerson has won 27 caps for Italy and played in their win over England in the Euro 2020 final at Wembley.
Emerson becomes West Ham manager David Moyes’ seventh signing since the end of last season.
West Ham lost 2-0 at home against Brighton on Sunday and sit bottom of the Premier League after three straight defeats, the club’s worst start to a season in 51 years.
