Erling Haaland‘s double earned Manchester City a 2-0 win at FC Porto – a valuable away victory to open their latest UEFA Champions League group campaign – but it was another night when Enzo Maresca’s side took three points without fully convincing.

City’s leading striker was unusually profligate before the break. Haaland passed up two clear openings inside the area, both denied by Diogo Costa, and sent a free header over the bar from another promising position as the visitors repeatedly carved Porto open but failed to make dominance count.

Porto’s goalkeeper delivered an outstanding first-half display, pushing away a low Haaland effort and then reacting sharply to stop Rayan Cherki on the rebound. Those interventions kept the Portuguese champions level at the interval and preserved an intimidating home record at the Estadio do Dragao that would eventually fall.

Haaland responds after wasteful first half

It took Haaland just two minutes of the second period to atone. The Norway striker overpowered Jakub Kiwior to reach an Enzo Fernandez cross, his header bouncing in off the post to give City a lead their territorial control merited.

Rather than killing the contest, however, the goal appeared to drain City’s urgency. Maresca’s side retreated a few yards, their passing lost its earlier precision, and Porto began to advance with more belief, energised by a home crowd unaccustomed to seeing their team trail on this ground in 2024.

Although Porto did not register a shot on target across the 90 minutes, they came close as Alan Varela stepped onto a loose ball on the edge of the area and curled just wide of the far post – a warning that City’s slackness in possession could yet be punished at this level.

Donnarumma’s scare and Haaland’s record-equalling finish

City were almost the architects of their own problems when Gianluigi Donnarumma, under pressure from Porto forward William Gomes, was nearly dispossessed inside his own box. The goalkeeper escaped as the loose ball trickled behind to safety, but the episode underlined how fragile City’s grip on the match had become.

The visitors finally secured the result in stoppage time. Substitute Rayan Ait-Nouri broke to the byline down the left and cut the ball back for Haaland, who arrived in the area to steer home his second goal of the night and confirm a 2-0 victory.

Haaland’s double not only delivered three points; it also carried individual significance. His 36th Champions League strike for City pulls him level with Sergio Agüero as the club’s joint-highest scorer in the competition, underlining how quickly he has re-written the modern European scoring records at the Etihad.

For City, starting the group phase with an away win in such a demanding venue eases early qualification pressure. In a format where every group game contributes directly to progression and seeding, banking three points on the road gives Maresca valuable breathing space as fixtures accumulate across domestic and European fronts.

Maresca’s away record and the Dragao benchmark

The performance, though, will not erase wider concerns about City’s form. The club arrived in Portugal on the back of a stuttering opening to the season: a heavy defeat in the Community Shield against Arsenal, a late escape at home to Bournemouth, a more fluent victory over Crystal Palace and then a narrow 1-0 win over Coventry in which control again ebbed away.

Set against that backdrop, this was another outing where the reigning Premier League champions took the points but left the impression of a side still searching for fluency. City became the first team this calendar year to beat Porto at the Estadio do Dragao, a meaningful benchmark given the stadium’s reputation and the Portuguese champions’ consistency on home soil.

For Maresca personally, the result helps to address questions that followed him from his previous job. The City head coach failed to win any of his three away Champions League ties as Chelsea boss last season; leading his new side to victory in one of Europe’s most challenging arenas offers an early signal that he can manage high-stakes away nights more effectively with this squad.

Manchester derby looms after imperfect win

Yet the manner of the display ensures scrutiny will not fade. City’s drop in intensity after taking the lead – the loose passes, slower pressing and vulnerability in transition – provided a blueprint that upcoming opponents will study closely.

Those concerns are sharpened by the domestic schedule. City now turn quickly towards Sunday’s Manchester derby at Old Trafford, live on Sky Sports, in what is traditionally one of the defining fixtures of the Premier League calendar. For United, exploiting any nervousness in City’s build-up play will be central to their plan; for Maresca, tightening that aspect of his side’s game is now urgent.

Kick off 4:30pm

Key moments at the Estadio do Dragao

16: SAVE! Antoine Semenyo starts the game brightly and curls an early effort into Diogo Costa’s gloves.

21: BIG CHANCE FOR HAALAND! Semenyo feeds Phil Foden, who clips a cross into the box for Haaland – the forward is denied by a sharp stop from Costa.

27: BIG MISS! Haaland heads over another good chance from a Semenyo cross from the left.

29: BIG SAVE! Foden embarks on a weaving run in and around the penalty area and forces another strong save from Costa.

31: DOUBLE SAVE! Costa first blocks Haaland’s low drive from inside the box, then recovers to deny Rayan Cherki on the rebound.

42: OUCH! Marc Guehi catches Gabri Veiga with his arm, causing heavy bleeding. Porto appeal for a red card for violent conduct, but the City defender goes unpunished after what appeared more accidental than malicious contact.

47: GOAL! Haaland takes just two minutes of the second half to atone for earlier misses, nodding a header in off the post from Enzo Fernandez’s cross.

49: NO PENALTY! City goalkeeper Donnarumma collides with Porto winger Pepe in the area, but the offside flag is raised against the forward to halt the attack.

57: SO CLOSE! Porto midfielder Alan Varela is given room to shoot and curls just wide of the far post. It is Porto’s first attempt of the game and a reminder of City’s fading control.

66: NERVY! Donnarumma is nearly caught in possession by Porto forward Gomes, but the ball runs behind for a goal kick.

85: JUST WIDE! City substitute Ait-Nouri breaks forward and has the opportunity to wrap up the match but drags his shot wide from a promising position.

90+1: GOAL! Ait-Nouri recovers from that earlier miss, reaching the byline on the left and cutting the ball back for Haaland, who finishes clinically to make it 2-0.

Haaland and Maresca reflect on a demanding night

Man City striker Erling Haaland to Amazon Prime:

“I hope so, we win away in a difficult game. Look at this atmosphere, it was unreal at times. So I hope [yes].

“Amazing game against the champions of Portugal. We knew it was going to be a difficult fight, man against man. They’re a top team, impressive, all of them. They play amazing football.

“Well done to them. But with all the pressure, we have to deliver on the biggest stage. That’s what we did tonight.

“Honestly we controlled the whole first half. Of course, it’s a bit uncomfortable when they come high. But we created a lot of chances. I could have easily had a few more goals.

“But second half we scored and they managed to push us for a good 25 minutes. We managed to hold through and finish the game.

“These are the games we have to win. We had a great start to the season and in the Champions League, you have to win games. If not, you get all the pressure. You never know what’s going to happen.

“We have to learn. Enzo has to demand a lot from us and each other. At Manchester City, you have to win games and win trophies, that’s what we have to do.”

Maresca pleased with result, aware of margins

Man City head coach Enzo Maresca to Amazon Prime:

“We could have scored more goals, especially in the first half. But overall we deserved to win the game. We created enough chances to win the game, we didn’t concede a lot.

“It’s normal to come here and concede some noises so overall I’m happy with the performance.

“If you think you’re going to come here in this stadium and just play and not concede anything, it’s not reality. It’s normal that they are going to create something. They didn’t create a lot – some actions, some mistakes from us. But I think it’s normal.”

Analysis: City still playing close to the edge

Maresca is right to highlight both the difficulty of the assignment and the control City exerted for long spells. Winning away at FC Porto – in a stadium renowned for its atmosphere and in a competition governed by fine margins – represents a result most contenders would gladly accept, especially early in the group stage.

But this performance also fits an emerging pattern. Across the opening weeks of the season, City have veered between dominance and vulnerability: a heavy defeat in the Community Shield, a late and somewhat fortuitous turnaround against Bournemouth, a more authoritative win over Crystal Palace and then a laboured success against Coventry in which their structure wobbled.

In Porto, City again dominated for 47 minutes before allowing the hosts back into the contest. The slack passes and repeated turnovers that followed invited pressure. A side with greater cutting edge in the final third might have transformed those moments into shots on target and, potentially, points dropped.

That inconsistency matters in a Champions League context. With group-stage points and goal difference feeding directly into progression and knockout seeding, repeated lapses could affect who City face later in the competition and whether they benefit from second-leg home advantage under UEFA’s competition framework.

What the result signals for City’s season

City leave Portugal with three important outcomes. They have an early foothold in their Champions League group, a high-profile away win that strengthens Maresca’s authority in the job, and confirmation that Haaland remains the decisive figure in tight contests, even when his finishing rhythm takes time to arrive.

At the same time, the match reinforced key areas for improvement:

• Maintaining intensity after scoring, particularly away from home.
• Reducing unforced errors in possession around their own penalty area.
• Translating control of territory and chances into earlier, more decisive scorelines.

Those details will shape the next phase of City’s season. With the Manchester derby at Old Trafford up next and more group fixtures to navigate, this win in Porto feels less like a statement of complete authority and more like a reminder that Maresca’s City remain a work in progress – dangerous enough to beat strong opposition away, but still close enough to the fire that one misstep could yet prove costly.
