Everton went into the international break on the back of a victory over Chelsea and it picked up where it left off to boost its hopes in the race to finish seventh, which could lead to UEFA Europa League qualification.

Zouma headed the visitors in front early on and Bernard doubled their advantage with his first Premier League goal against the limp Hammers before half-time.

A change in formation at the break brought about an improvement from the Hammers, but they failed to get a single shot away in the second half and were booed off after a defeat that left them 11th.

Everton took the lead inside five minutes when Zouma rose above Issa Diop to head Gylfi Sigurdsson's corner home and the visitors quickly sought another in an open start.

Lukasz Fabianski did brilliantly to keep out Dominic Calvert-Lewin and Sigurdsson in quick succession before Lucas Digne cut in from the left and saw his curling shot pushed behind.

West Ham eventually found its footing, but Seamus Coleman combined with Richarlison to get in behind and square for Bernard to tap into a gaping net in the 33rd minute.

Manuel Pellegrini responded by shuffling his pack, sending on Javier Hernandez and Michail Antonio for the second half, with the Hammers quickly enjoying more possession with an extra man in central midfield.

Jordan Pickford remained largely untroubled, though, and Marko Arnautovic, who had been moved out to the left wing, was sacrificed for Grady Diangana in the 67th minute, although he appeared to be struggling with a knee injury.

Marco Silva's side was denied a third when Richarlison's powerful header crashed back off the crossbar in the 83rd minute, but enough had been done to close the gap to seventh-place Wolverhampton Wanderers to just one point.
