Haaland netted either side of the break, first heading home from Savinho’s delivery to put City two to the good, with the Brazilian having played a key role in the hosts’ opener when his cross was turned inadvertently in by Vladimir Coufal.

Savinho also teed up Haaland’s second to make it 3-0, with the Norwegian delicately lifting the ball over the onrushing Alphonse Areola.

Phil Foden then ruthlessly punished a mistake at the back by the Hammers, sliding the ball home after being picked out by Kevin De Bruyne on his 400th appearance for City in all competitions.

The visitors grabbed a consolation when Niclas Fullkrug swept in Tomas Soucek’s cross in the 71st minute, but the damage had already been done.

Pep Guardiola’s team remains sixth on the table, two points adrift of the top four, while West Ham remains 13th, having conceded nine goals in its past two Premier League games.

De Bruyne and City coach Pep Guardiola showered praise on Savinho after the game.

Four of Savinho’s five Premier League assists this season have been for Haaland, the joint-most from one player to another in the competition this term.

"I think the talent is really there. He started really well this season and then went a bit down like the whole team, which is normal," De Bruyne said.

"But he has exceptional qualities, so it is good he has confidence and makes the difference for us."

"He was brilliant. He is one of the few that is fresh. There were glimpses of brilliance. The work ethic was unbelievable, but still not the composure," Guardiola added.

"We accelerate everything. We have struggled with results recently, but the last two victories are good, and we did not lose in three games.

"I would say a month-and-a-half [of poor form] compared with eight years is not bad."

Having endured a difficult start to the season, which has seen it lose six of its first 20 top-flight games, De Bruyne believes his side is slowly getting back to its best.

"We know it has been a tough season, but I think today was an improvement from the last game," the Belgian added.

"Physically, we are starting to get better, so by playing games and winning we hopefully get some confidence, and it will get better."

Guardiola, however, was more reserved when asked about the magnitude of his team's latest win amid the injury crisis his squad is currently enduring.

"No [we are not back in the groove]. It is happier to win, but we are still not like we were for different reasons. The result will help. We struggle, but it is a release," the Spaniard said.

For West Ham, this defeat was the Hammers' sixth top-flight loss by a margin of three or more goals this season, more than any other side in the division so far.

But the visitors had their chances, with Soucek squandering a golden opportunity in the first half, while Lucas Paqueta and Mohammed Kudus also went close.

Soucek believes it was an opportunity missed for the Hammers at City, with the midfielder left to rue his side's missed chances during the contest.

“We are upset because we had a good chance to take the points from Manchester City," Soucek said.

"Especially in the first half, I had a good chance, and we had a few others, and then we conceded a deflected goal. We tried to compete, and we did, but the result was not good.

"We have suffered a few big defeats. We have one way which we build in training, which we wanted to show.

"In many ways, we did, but we have to try not to concede goals. Jarrod is a miss for us. This season, he has been great, but this is football, and we need to step up for him now.

"We showed more with the ball today. We had chances, but we need to concentrate on getting points."
