Manchester City recorded an eighth consecutive victory in all competitions as they swatted aside West Ham in the Premier League.

The game was over by half-time, with David Silva, Raheem Sterling and Leroy Sane all getting in on the act.

Silva poked home Sterling's deflected cross for the opener and Sane then rolled in a low cross for Sterling to tap into an empty net.

Sane added a fine third from Sterling's volleyed cross, with the German's touch leaving defender Fabian Balbuena on the ground, allowing him to slot home.

West Ham were much better in the second half and Michail Antonio hit the post - but Sane scored his second and City's fourth in injury time.

Manuel Pellegrini's Hammers side, who saw Marko Arnautovic hobble off late on, have now won only once in seven games.

City cruise at London Stadium again

The Premier League champions - who remain two points clear of Liverpool at the top of the table - have now played four games at West Ham's new stadium, scoring four or five in each one.

They were stylish and clinical in the first half and efficient after the break.

Some of City's football in the opening 35 minutes was what we have come to expect from Pep Guardiola's side. Sterling and Sane in particular were brilliant as they dominated possession with plenty of crisp passing.

Silva scored their opener from close range, although Sterling will not be credited with the assist as his cross took a slight deflection.

The two wide men combined for the second goal as Sane shimmied past Pablo Zabaleta and gifted Sterling a simple goal.

Sterling then set up Sane, who showed wonderful composure to turn round a defender and guide a shot into the net.

City are the only team not to drop a point from a winning position in the Premier League this season, so a comeback was never on the cards.

They only had nine shots in total and they looked comfortable, but not spectacular, in the second half.

In truth, Sane's injury-time fourth - from substitute Gabriel Jesus' cross - was harsh on West Ham.

Arnautovic injury a worry for Hammers

West Ham were thrashed once again by City, and have won only once since 29 September, but they perhaps deserved better than a 4-0 defeat in the end.

They were outclassed in the first half - although they made it easy for City - but they improved after bringing on the lively Aaron Cresswell at the break.

Antonio was unlucky to hit the outside of the post as he ran onto Javier Hernandez's raking through ball.

Arnautovic and Balbuena headed efforts over the bar as their chances for a consolation came and went.

Arnautovic was hurt by a fair Nicolas Otamendi tackle and tried to play on after treatment - but did limp off late on with all of West Ham's substitutions already used.

The Austria international is the club's top scorer this season with five goals.
