MANCHESTER CITY turned in a complete display as they outclassed West Ham to move level on points with fourth-placed Liverpool.
Pep Guardiola's men were on a different planet to the hapless Hammers as they raced into a three-goal lead before the break to leave Slaven Bilic's side stunned.
Kevin De Bryune opened the scoring before David Silva doubled City's lead on 20 minutes, and things got worse for West Ham when Gabriel Jesus rolled home the third.
City continued their onslaught after the break and Yaya Toure added a fourth from the spot as Guardiola's side rounded off a devastating display.

FACTS, STATS, GOALS AND LOLS

WEST HAM captain Mark Noble claimed The Hammers were out for revenge for the 5-0 home FA Cup defeat last month - but it hardly showed.
KEVIN DE BRUYNE got City off the mark with a tap in on 17 minutes after West Ham were sliced open when Aaron Cresswell gave up possession.
DAVID SILVA maked it 2-0 when he was left totally unmarked at the far post as City threatened to run riot.
AARON CRESSWELL was put clean through to give West Ham a chance of a comeback, but at the vital moment he lost control and ballooned his effort high over the bar.
GABRIEL JESUS scored his first goal in English football, and it was a gift, as City made it it three when Sofiane Feghouli and Pedro Obiang were involved in terrible mix up.
WINSTON REID was lucky not to get sent off when he scraped his studs down the side of John Stones’ head leaving a trail of blood on the City defender.
