West Ham came from behind to beat Romanian side FCSB in their Europa Conference League Group B opener.

The hosts dominated possession from the outset but fell behind in the 34th minute when Andrei Cordea scored at the far post.

Jarrod Bowen equalised after the break with a well-taken penalty after Maxwel Cornet had been fouled.

Emerson then struck from close range to make it 2-1 before Michail Antonio scored a late third.

West Ham could have added even more goals in a strong second-half showing, with Bowen, Pablo Fornals and Antonio all denied.

David Moyes' side have made a poor start to the Premier League season with just one win in six games but this was their third successive win in Europe after victories in qualifying.
