The pupil welcomed his former master to the Emirates – and for a moment, it seemed the old hierarchy would remain intact. 

Erling Haaland wasted no time, putting Manchester City ahead in the ninth minute and setting the stage for what seemed like a commanding performance.

However, as the match drifted into stoppage time, substitute Gabriel Martinelli managed to breach City’s defense, surging through to secure a dramatic 93rd-minute equalizer.

DONNARUMMA THE WALL

The 6ft 5in frame of Gianluigi Donnarumma was troubling Arsenal once again.

Back in April and May, he showcased his skills across two legs of the Champions League semi-finals for Paris Saint-Germain, making a series of formidable saves to stymie the Gunners.

He didn’t need to pull off spectacular saves in Manchester City colours but his command of his box, particularly from set-pieces, was clear.

The 26-year-old consistently reached multiple corners delivered by Noni Madueke and Declan Rice first, using his height and presence to punch the ball clear of advancing Gunners.

Set-pieces have often proven crucial for Arsenal, a team filled with players over 6ft who excel in aerial duels, particularly Gabriel and Mikel Merino.

Donnarumma’s methods were incredibly effective, prompting Arsenal’s set-piece coach Nicolas Jover on the sidelines to passionately gesture and instruct his players on breaching the defense.

Mikel Arteta said of City’s keeper afterwards: ‘He’s so dominant in the box, and every ball that is in and around the six-yard box. His timing, the way he executes the action is super-efficient, it’s very difficult and today again he made some very important contributions.’

If other teams are stuck when it comes to how to defend Arsenal corners, the Donnarumma blueprint is a good one to look at — particularly if their keepers have the height of the Italian.

WHAT GYOKERES CAN LEARN

If any team could stop Haaland, it was likely to be Arsenal. The Gunners had restricted City’s forward to just two shots in four matches before Sunday’s clash.

Yet it took the Norwegian just nine minutes to strike, picking the ball up from before the halfway line, orchestrating a give-and-go with Tijjani Reijnders and outpacing Gabriel into the box.

He then coolly slotted the ball past Raya with his weaker right foot, nonchalantly ambling away upon scoring.

He’s in fine form, of course: five goals for Norway against Moldova last week was followed with strikes against Manchester United and Napoli. And his goal reflected just what Arteta has so desperately lacked in recent times: a goal machine who just needs that one chance to make the difference. They hoped they’d found one by signing Viktor Gyokeres, who barely had a touch in the box, took no shots and managed just eight passes.

His team-mates still seem to be adapting to his style of play, failing to find him when he broke through the lines which left the striker constantly coming short with his back to goal to receive the ball.

When asked about the lack of service to Gyokeres, Arteta said: ‘Well, there were a lot of very good balls in the box, especially I remember three of them that he was very, very close to doing it against City.

‘To have very big open chances is extremely difficult, but he’s certainly trying his best and trying to do that, and we have to provide more for him — that’s it.’

But the truth is that when he did receive possession, Gyokeres wasn’t able to make an impact the way Haaland did. Arsenal must rectify this as getting Gyokeres firing is a must.

THE CALL ARTETA GOT WRONG

One talking point as soon as the teamsheets came out was Arteta’s decision to start Leandro Trossard.

Gabriel Martinelli looked to be in contention for a start following his heroics against Athletic Bilbao but was named on the bench alongside Eberchi Eze and Bukayo Saka, who is returning from injury,

Trossard, having yet to start a game this season before today, came with a point to prove. The diminutive Belgian had a couple of shots blocked and kept looking to play incisive passes forward.

The squad depth Arteta possesses has created this competition and it means those on the fringes, like Trossard, head into rare starts with a point to prove.

But it was Martinelli who again stole the headlines with his late leveller. And he proved that starting Trossard over him – and Eze – was the wrong decision by Arteta.

Martinelli’s stunning late equaliser was evidence that Arteta had made the wrong call

The Brazilian came on after 80 minutes and had an immediate impact, driving forward with vim at the opposition backline.

His sublime chip took solid execution under pressure. It was the result of an impressive ball over the top from Eze in his own half.

It was the kind of magic needed to break a Man City low-block which featured five defenders in the second half.

Arteta did decide to bring on Eze and Saka at half-time – and that reflects how much depth he has in the frontline.
