PREM: West Ham 0-4 Manchester City

David Silva grabbed City's second goal from close range in the first half

Manchester City cruised to a 4-0 win against West Ham to stay top of the Premier League and keep their unbeaten start intact.

Pep Guardiola's team put in a ruthless display at the London Stadium and victory was as good as confirmed in the first half thanks to strikes from David Silva (11), Raheem Sterling (19) and Leroy Sane (34).

Sane (90+3) rounded off an emphatic victory deep into stoppage time as City, who made it eight wins out of eight in all competitions, stayed two points clear of Liverpool, who beat Watford 3-0 at Vicarage Road, at the top of the Premier League.

For Manuel Pellegrini, his first meeting against his former side did not go to plan as West Ham stay 13th, four points ahead of the relegation zone.

Silva sent City on their way with his fourth goal in as many games as Sterling's cross deflected off Arthur Masuaku and into the path of the Spaniard, who had a simple finish to beat Lukasz Fabianski from close range.

West Ham did threaten in attack but they lacked a cutting edge in front of goal as Marko Arnautovic and Michail Antonio wasted two good opportunities.

They were made to pay when Sane burst past Pablo Zabaleta before driving the ball across goal for Sterling to tap in from close range.

Sane himself added the third after being picked out by Sterling's cross. The German showed great composure in front of goal, feinting to shoot to take Fabian Balbuena out of the game before beating Fabianski from close range.

Sterling went close to adding his second of the afternoon shortly after the break but Fabianski produced a fine block to deny the England international.

At the other end, West Ham's poor finishing continued as Antonio, who was sent clean through by substitute Javier Hernandez, saw his shot clip the outside of the post.

There were worrying signs for West Ham as Arnautovic limped off in injury time, leaving West Ham a man short for the final few minutes.

And there was still time for City, who have now scored 17 goals in only four visits to Stratford, to add a fourth, Sane striking from close range to round off another comprehensive win in east London.
