Salah at the double as Liverpool increase the pressure on West Ham and Bilic

The Egypt striker started and finished the rout at the London Stadium, where Liverpool also had Joel Matip and Alex Oxlade-Chamberlain on target.

Manuel Lanzini found the net for West Ham, but the struggling Hammers were well beaten in a defeat to heap yet more pressure on beleaguered boss Slaven Bilic.

West Ham have just nine points from 11 matches - the same tally at this stage of the 2010/11 campaign that saw them relegated.

Salah's 11th and 12th goals in all competitions this term took Liverpool back to sixth on goal difference, after Burnley had briefly leapfrogged the Reds on Saturday afternoon.

Sam Vokes headed Burnley to a short-lived stay in sixth place as the Clarets edged home 1-0 at Southampton.

Striker Vokes ended a five-match barren league spell with his first Premier League goal since scoring twice in the opening-day 3-2 win at Chelsea.

Southampton pushed hard throughout the second half but Sean Dyche's men prevailed by netting the game's only goal.

Dyche showed again why he is in such demand and linked to the vacant Everton managerial role, as he masterminded another important win for his high-flying Clarets.

Glenn Murray claimed his fourth goal in three Premier League games to hand Brighton a 1-0 win at Swansea.

The former Crystal Palace striker bundled the ball home with his thigh in an untidy but pivotal finish for Chris Hughton's Seagulls.

Rajiv van La Parra curled home a fine strike for his maiden Premier League goal as 10-man Huddersfield held on for a 1-0 home win over West Brom.

The hosts had Christopher Schindler sent off for two bookable offences but were still able to grind out an impressive victory.

Steve Cook's added-time goal stole Bournemouth a vital 1-0 win at Newcastle, moving Eddie Howe's side out of the relegation zone.

Cook's late header ensured Howe's men claimed just their second league win since September.

The St James' Park clash appeared to be heading for a dispiriting goalless draw, especially when Marc Pugh missed a gilt-edged chance for Bournemouth late on.

But at the last Cook popped up to rise highest from a corner and head the Cherries to a deserved victory.

Xherdan Shaqiri curled in a free-kick then laid on a Peter Crouch header as Stoke twice came from behind to grab a 2-2 draw at home to Leicester.

Vicente Iborra and Riyad Mahrez found the net for the Foxes, as new boss Claude Puel extended his unbeaten start with the east Midlanders.
