Matheus Nunes

Haaland, who returned at the end of January from nearly two months out, grabbed the headlines with his finishing but this 6-2 win owed every bit as much to De Bruyne, the architect of four of his team-mate’s haul and a devastating creative presence throughout.

The pair combined for City’s opener inside three minutes. Matheus Nunes fed the Belgian with a clever reverse pass, releasing him into a channel down the left, and the cutback came to the left foot of Haaland who wrapped his boot around it for 1-0.

The same combination created the second, this time a pass threaded through the middle ended with Haaland fending off defender Teden Mengi and crashing it through the legs of Tim Krul.

The third arrived before the break, with VAR required to adjudicate that the Norwegian had successfully stayed onside as he set off to reach De Bruyne’s through-ball, chipping his finish over the goalkeeper.

Luton fought gamely in spite of the Haaland onslaught. Jordan Clark curled one brilliantly beyond Stefan Ortega at the end of the half, offering Rob Edwards’ side hope, before thumping in another at the near post after the break as the home fans sniffed a famous fightback.

They were given all of three minutes to dream. Haaland and City’s fourth was another tap-in from yet another De Bruyne set-up. The fifth cruel on Krul, the ball squirming through the goalkeeper’s body as the cup holders’ top scorer finally declared.

Mateo Kovacic hit a sixth, and Luton could breathe for the final few minutes after Haaland was withdrawn.

“The players read the game perfectly,” said Guardiola. “The connection of Kevin with Erling was great but everyone contributed. Happy to be in the quarter-finals, one game away from Wembley.

“Erling needs a guy with the vision, the quality, the generosity. Kevin is the less selfish player in front of goal. Kevin needs the movement from Erling. We know how aggressive they are.

“Every pass was good. The finishing from Erling was good. We could have scored more, we had two or three more chances, one against one with Krul. But the players read (the game) really well. They did it perfectly.

“My only concern was that Erling had been two months stopped, he couldn’t walk, couldn’t make anything. When you lose two months, that rhythm is not easy to get back.

“Every game he’s getting better. Kevin as well. Step by step, they are coming back.”

The game was only marred for City by the loss of a visibly upset Jack Grealish just before half-time to injury.

“I didn’t speak to the doctor but I think he was complaining a bit about his groin,” said Guardiola. “He felt really good but unfortunately was injured again.

“It’s been a tough season for him. He’ll have to recover well and help us when he’s able to come back.”

Luton boss Edwards reflected on a masterclass from De Bruyne and Haaland.

“There’s no doubt about it, they were incredible,” he said. “The played in the space we gave them and did it very well. But our lads were incredibly brave and bold, and stuck to the task.

“We’re not going change, we just need to get better, to keep improving.”

Roberto Martinez's team did not let up after Rafael Leao lashed them ahead in the 24th minute, with Matheus Nunes and Bruno Fernandes putting them three to the good by half-time.

Bruma made matters worse for Sweden before in-form Sporting CP forward Viktor Gyokeres netted at the other end, albeit that goal should have been disallowed for offside.

Goncalo Ramos rounded off Portugal's rout just after the hour, though Gustaf Nilsson did grab another consolation for Sweden in the final stages.

Leao's strike was just his fourth for the Selecao, with the winger hitting his shot sweetly after controlling the rebound from Bernardo Silva's effort off the woodwork.

Portugal's control was cemented just after the half-hour mark, as Silva set up his Manchester City team-mate Nunes for a composed finish from outside the box.

Sweden were punished for more slack defending on the stroke of half-time – Fernandes left free in the six-yard box to power a shot high into the back of the net, taking his international tally to 20 goals.

The hosts started the second half with the same intensity, and Fernandes' pressure paid off when he blocked a clearance and set Bruma up for a tap-in. Just 91 seconds later, Gyokeres pulled one back for Sweden from an offside position, but with no VAR, the goal stood.

Ramos restored Portugal's four-goal lead shortly after, with his eighth goal in 10 international appearances adding further gloss to another fine win under Martinez, though Nilsson – who had earlier tested Rui Patricio with an audacious attempt – ensured Sweden had the final word.

No Ronaldo, no problem

Portugal were without their biggest star in Guimaraes, with Cristiano Ronaldo the most notable absence from the team sheet. But it is not like they struggled without the 39-year-old.

The Selecao have scored 36 goals in their perfect Euro 2024 qualifying campaign, the most of any nation during that time, and they clocked up another five with ease.

Perhaps even more pleasing to their coach, the goals were spread among his midfield and forward line, with Bruma also coming off the bench to make an impact.

They might have gone under the radar, but Portugal could be the ones to watch in Germany come June.

Tomasson's big changes fail to pay off

After playing in a rigid 4-4-2 formation under Janne Andersson, Sweden deployed a more attacking set-up under Jon Dahl Tomasson on Thursday, with Newcastle United star Alexander Isak playing behind Gyokeres, who is thriving in Portugal this season.

It showed the promise of paying off in the second half, with Gyokeres getting his goal just before the hour-mark, but by then it was already too late for them to mount a real comeback, and Nilsson's effort did nothing more than restore a tad more pride.

Three of Portugal's goals were simple tap-ins, with the Selecao's scorers left with an empty net to aim for, and that slack defending will frustrate Tomasson.
