Images tinged with sky blue are printed on a wall that rises alongside one of the staircases at the Etihad Stadium. One of them shows Vincent Kompany, hotly pursued by Bernardo Silva, wheeling away after he had scored the critical goal against Leicester City that helped Manchester City win the league in 2019.

The legend underneath it reads: Where do you want your statue?

There are pictures of Neil Young and Georgi Kinkladze and Gabriel Jesus, all taken after they had scored decisive goals in a City season. And so, of course, at the top of the staircase, there is a picture of Sergio Aguero scoring the goal that won City’s first title for 44 years in 2012.

‘Manchester City are still alive here,’ the phrase written above it says.

Now there will be another picture on the wall, more iconic moments to treasure, more beautiful goals to acclaim, more City heroes to celebrate. There were four goals to choose from last night but if City’s one-sided victory really was a title decider, it was decided in the seventh minute when Pep Guardiola’s side fashioned a magnificent opening goal that was created and finished by the two poster boys of City’s increasingly irresistible and lustrous season, Erling Haaland and Kevin de Bruyne.

De Bruyne is a City hero who would grace any era and his strike was just the start of a game that was billed as a shoot-out but turned into an execution by firing squad. City were imperious. This is a high bar, but even by their standards, this was a performance of breath-taking brilliance.

Arsenal, who were eight points clear at the start of the month, have had a wonderful season but they were completely outclassed by the champions here. The average age of Mikel Arteta’s players is 24.4 years and last night, it looked it. It was men against boys.

City still need to win six of their last seven matches to be sure of becoming champions for a third successive season but even though they are still two points behind Arsenal with two games in hand, the manner of their victory here suggested they will sprint to their third title in a row and their fifth in six years.

Arsenal looked so overwhelmed that it is hard to see them sustaining their challenge in the five games they have left.

This 4-1 humbling was the Gunners’ 12th successive league defeat to City and will probably condemn them to a 20th year of searching for their first title win since the Invincibles victory of 2003-04. City were the team who looked invincible last night. Their football was irresistible. They had too much for Arsenal in every single department. This win took them a giant step closer to winning the treble.

This was barely a contest. It was an evisceration. It was a humiliation. It was a lesson. It was the most formidable statement of intent any team has made in the Premier League this season. Arsenal might be the pretenders to City’s crown but City put them back in their box last night and slammed the lid shut. They have now won 13 of their last 14 games in all competitions. The masters of the late-season charge, they appear to have done it again.

The sense of anticipation before the game was so elevated not just because of the repercussions it held for the title race but because the football that City and Arsenal play represents so much that is good about the sport. At different times in this elongated season, their play has been a delight to watch.

Every time Erling Haaland plays, it is like watching history as he launches his full-blooded assault on English scoring records. His only real rival for the Footballer of the Year crown is Bukayo Saka, although Martin Odegaard is not far behind either of them. Kevin de Bruyne is back to his bewitching best, Jack Grealish has matured into an elite player, John Stones has been superb in the hybrid right-back-holding-midfield role Guardiola often uses him in.

William Saliba would have been on that list, too, were it not for the back injury that, once again, ruled him out last night. His absence has coincided with the slump that has seen Arsenal’s form stutter and drift. His replacement, Rob Holding, struggled so badly to control Haaland when Arsenal played City in the FA Cup fourth round in February that he was booked in the first half and then substituted at half time.

A giant banner which read ‘I’ll Follow You Everywhere’ covered one side of the ground as the players came out for the kick-off and there was a reminder of the 115 financial charges that City are facing when the Premier League anthem was booed.

Guardiola and Arteta did their bit to restore brotherly love when they wrapped each other in a hug on the touchline.

Arsenal were fortunate not to concede a penalty inside the first two minutes. City tore into them from the start and when Grealish drilled in a cross from the left, Aaron Ramsdale spilled it at full stretch and it trickled into the path of De Bruyne. De Bruyne was about to force the rebound home when Thomas Partey appeared to take his legs out from under him. Referee Michael Oliver waved play on. VAR agreed with him.

It was a brief reprieve for Arsenal. Five minutes later, Stones hoisted a long ball out of defence and Haaland cushioned it on his chest, shielding it brilliantly as Holding tried desperately to dispossess him. Haaland laid the ball off to De Bruyne and this time the Belgium playmaker would not be denied. He ran at the retreating Arsenal defence, turned Gabriel inside out and curled his shot beyond Ramsdale’s despairing left hand.

It was a stunning goal but while City’s outfield players and the home fans celebrated wildly, Guardiola rushed over to Ederson and remonstrated with him, imparting instructions with animated urgency. Guardiola’s mind never sleeps.

The atmosphere inside the Etihad was febrile, just as Guardiola wanted it. He did his bit to fan the flames, too, stamping his feet and waving his arms and protesting furiously when the referee penalised Bernardo Silva for a foul on Partey.

Midway through the half, City nearly doubled their lead. Haaland played De Bruyne in again, De Bruyne turned Gabriel inside out again but this time, his shot was blocked by Ben White.

A couple of minutes later, Haaland went for goal himself, scything through the Arsenal defence, surging into the box before his shot was saved. ‘Stand up for the Champions’ rang around the ground.

City were utterly dominant. Arsenal had no answer. Grealish, De Bruyne and Haaland were tormenting them. They were toying with them.

Haaland ran at their defence again 10 minutes before half time and moved the ball on to his left foot. When he shot, the stadium waited for the net to bulge. It went just wide, sending Ramsdale’s water bottle spinning and flying instead.

City finally added a second on the stroke of the interval when Stones rose at the back post to power home a free kick from De Bruyne.

A linesman’s flag seemed to have ruled the goal out for offside but it was checked by VAR and the goal was allowed to stand. Stones had been played onside by White’s boot. The stadium erupted in ecstasy all over again.

The Norwegian hitman took his remarkable goals tally to 49 for the season across all competitions, sealing City’s 4-1 triumph

Even if it was only a formality, City put the game out of reach eight minutes into the second half. Haaland should have scored a few moments earlier when he went clean through but saw his shot saved by Ramsdale’s legs.

It didn’t matter. If he was having trouble scoring, he was having a dream night creating goals for others. When Odegaard lost the ball cheaply in his own half, De Bruyne played the ball to Haaland, raced on to the return and threaded his shot through the legs of poor Holding and into the net.

City’s tempo dropped a little after that but Arsenal knew there was no way back. So many of the players who have made them so good to watch this season disappeared last night. They were overrun. They were anonymous.

As the game wore on, embarrassment, then frustration, then anger, began to take hold and Partey and White were lucky to stay on the pitch. Holding swept in a late consolation goal but it did nothing to disguise the fact that, for the visitors, it had been a chastening night.

Arsenal’s misery was complete when Haaland finally got the goal he deserved, his 49th of a remarkable individual campaign, with practically the last kick of the game.
