West Ham came from behind to claim a 3-1 win over Romanian side FCSB in their Europa Conference League Group B opener.
The Hammers fell behind in the 34th minute when Andrei Cordea scored at the far post.
Jarrod Bowen was immense for the Premier League, equalising after the break with a well-taken penalty after Maxwel Cornet was fouled.
Emerson then struck from close range to make it 2-1 before Michail Antonio scored a late third.
David Moyes' managed 21 shots throughout the match, and the Scotsman will be hoping this form can translate to the Premier League.
The east London side next host Newcastle United on Sunday.
