The defeat – Everton’s sixth in their last seven league games – will add to the pressure on manager Frank Lampard, while for West Ham boss David Moyes victory will be sweet relief after his side took just one point from the last 21 available.

Bowen scored his goals in a seven-minute first half spell, first netting from close range after Emerson Palmieri’s cross was flicked into his path.

He was set up for his second by good work on the right wing by Michail Antonio, whose cross was timed perfectly for the incoming forward.

Everton went close late in the half when Alex Iwobi’s goal-bound effort was deflected onto the woodwork by Declan Rice, and they were much improved in the second half but could not find a way back into the game.

It is more misery for Everton fans, who had a sit-in protest at Goodison Park last weekend following defeat to Southampton, calling for the club’s board to be sacked. Those calls will likely grow louder in the coming days.

West Ham are next in action in the FA Cup fourth round when they travel to Derby County on Jan 30, while Everton host leaders Arsenal in the Premier League on Feb 4.
