It was a clinical, ruthless display at the London Stadium as City scored five goals without reply to dismantle West Ham and take three points.
Here’s the best of the media reaction…
Nick Miller: “Still, it's going to take more than VAR to stop Manchester City this season. Having watched Liverpool stick four past Norwich on Friday, City echoed last season by going one better on Saturday. It probably could have been more than the eventual margin of victory, as Pep Guardiola's relentless machine showed up and, in the second half at least, battered a perfectly decent West Ham side.
“City enjoy playing here. They have now played at the London Stadium five times since West Ham made this their home in 2016, and they've scored 23 goals. In the 19 league games of their first season here, West Ham managed 19.
“In terms of the football at least, this was a game in which we essentially learned very little -- or very little new, anyway. Manchester City looked exactly as they always have under Guardiola: rapid, ruthless and imposing.”
Sam Wallace: “Sterling scored a hat-trick, enduring another VAR check for his beautifully taken second goal. The Englishman picks up where he left it last season and so too City who demolished a new look West Ham with the usual overloading of players in key areas of the pitch and clinical finishing. Manuel Pellegrini argued that his team had not been overrun in the first half but even he was a little embarrassed by the margin of defeat. The summer investment might turn out to have improved West Ham but City are still playing a very different game.”
Manchester Evening News: Rodri shows Man City fans why Pep Guardiola is so excited
Simon Bajkowski: “From the first whistle, he popped up wherever the ball was - a regular output for Ederson on the edge of the box, arriving on cue to clear the ball or spraying passes forward for those ahead of him to run onto.
“It was not a perfect performance; twice he was caught on the edge of his own box and it was only his strength that helped recover the situations. But both of those parts are why City rate him so highly in that he plays on the edge and has more of a physical presence than almost all of his teammates.
“Guardiola believes his experience at Atletico will be of great benefit and when the Spaniard was knocked down by a stray arm from Michail Antonio in the first half, if there was one voice inside his head questioning his welcome to English football there was probably also Diego Simeone urging him to get up and get on with the game.
“Rodri will surely improve and cut out the mistakes as he gets more used to his league and his team, but if he is this omnipresent already no wonder he has his manager purring.”
