As the players dropped to the turf at the end of an exhausting North London derby, the sense among the home fans at the Emirates would have been familiar.
They have seen this all before here, watching in anguish as their defence melted under the slightest heat and then roaring in joy as their attackers made up for it at the other end.
This time around, though, there were different characters in the story. Alexandre Lacazette and Pierre-Emerick Aubameyang are two of the usual protagonists, yes, but here they were joined by two others.
Nicolas Pepe's involvement was to be expected, given Arsenal's £72 million outlay on the winger this off-season, but the same cannot be said for Matteo Guendouzi, perhaps the least likely hero of the day, but the hero all the same.
Unai Emery, the Arsenal head coach who looked to have aged a decade during a fraught 90 minutes, likes to speak about "mentality". He wants characters on the pitch and strong personalities on the ball. In Guendouzi, still only 20 years old, he had a midfield leader who drove Arsenal forward when so many of his teammates looked lost.
Big hair, bigger heart. Guendouzi ran, tackled, intercepted, passed and ultimately created the key moment for Arsenal, curling in a delightful cross for Aubameyang's second-half equaliser. He was also involved in Lacazette's goal, winning the ball high up the field to start the move that reignited Arsenal's belief.
In only his second season in England, Guendouzi showed a spirit missing among more senior members of the team, particularly in the first half.
Arsenal's midfield was not functioning and two of their more experienced players, Granit Xhaka and Sokratis, had damaging roles to play as Tottenham Hotspur took a two-goal lead.
Arsenal needed drive and inspiration. They found it in the usual suspects up front, but also in Guendouzi, who arrived from Lorient for just £7 million last year.
"He is very young but he is progressing," said Emery. "Last year was amazing for him. This year, he has started giving us one step more. Tactically, with the ball, he gives us a lot of control."
Emery insists his side must be adaptable enough to adopt different shapes and systems from week to week. In many ways, it is a strength of the modern Arsenal, and it certainly helped them in this fixture last season, when they swapped between three formations on the way to winning 4-2.
There are occasions, though, when the players simply look uncomfortable with what they have been asked to do. Rarely has it been more evident than in the first 45 minutes yesterday, when Arsenal's midfield was stretched and misshapen against a Tottenham attack that simply could not believe the space they had been given. Lucas Torreira, his little legs whirring as fast as they can, kept charging out to the right wing. On the other flank, Guendouzi drifted left.

It all meant that Xhaka was left manning the fort in the centre. As anyone who has seen Arsenal in recent years would attest, this is a situation of considerable peril. He soon charged in on Son Heung-min, sliding into a tackle with all the grace of a truck on an ice-rink. Harry Kane inevitably scored the penalty.
Xhaka remains a strange and infuriating player for Arsenal. He is both an essential member of the squad, the captain this season, and also a permanent liability in defensive moments. His foul on Son was almost as brainless as the penalty he conceded in a damaging draw at home to Brighton last season.
With every year, he becomes a more senior part of the team, growing into a genuine leader and taking the armband, but still the same old mistakes blight his game.
In these early exchanges, Arsenal looked bewildered by the movement and angles in the Tottenham midfield.
Harry Winks was dominant, all swerving hips and delicate touches, while Son was a permanent threat on the counter-attack.
Arsenal reeled, on the verge of a collapse similar to their meltdown at Anfield last weekend, but they steadied themselves before Spurs could swing another fist.
Crucial to that, as ever, were Aubameyang and Lacazette, who were aided by Pepe, the latest addition to their freewheeling clique.
The excitement around Pepe manifested itself in a growling hum that rolled around the Emirates whenever he received the ball.
With Lacazette dropping in and Pepe and Aubameyang pushing on, Arsenal's front three at times had echoes of Liverpool's edition, where Sadio Mane, Roberto Firmino and Mohamed Salah incite so much fear in opposition defences.
This was the first time Pepe, Aubameyang and Lacazette had started a match together.
To say they had been unleashed would perhaps be an overstatement, given Tottenham's control of the first half, but there can be no questioning the role they each played in the comeback.
There was Pepe, flicking a cross to Lacazette at the end of the first half.
