The celebrations spoke as loud as they sounded.
Carlo Ancelotti and his staff erupted in joy, making a unified beeline for the pitch.
Everton's players scampered after goalscorer Dominic Calvert-Lewin and screamed their delight.
Striker Calvert-Lewin had sent a full-blooded header thudding past Hugo Lloris before the goalkeeper could react. Everton, regaining the ascendancy they'd enjoyed in the opening half-hour, had the goal their pressure merited.
This was the tangible success to crown a week when Everton have made headlines the world over for their business in the transfer market.
A message that ambition off the field would be matched on it. The unanimously joyous reaction to Calvert-Lewin's finish after meeting Lucas Digne's flat left-wing free-kick suggested a togetherness already developing in this squad.
Those three new players were excellent to a man, influential in this victory. It felt appropriate somehow that the striker signed from Sheffield United four years ago, who has developed so notably in the past 12 months, should have the decisive say.
This was Everton's first win at Tottenham for the best part of 12 years. And it was no smash and grab either. Everton were mature, composed and controlled. Anything other than an away win would have felt unjust.
Everton’s aggression and purpose in the opening exchanges disrupted Tottenham.
There were no easy passes for the home team and scant time to breathe in possession.
Perhaps this contributed to Ben Davies’s rushed pass which gave Everton the game’s first clear chance.
Welshman Davies had more time than he realised but rushed a pass which missed its target, namely Toby Alderweireld, by a distance.
Alderweireld was suddenly in a race he was never going to win, chasing down the ball with Richarlison eyeing the same prize as he hared forward on Everton’s left.
Richarlison inevitably got there first, escaping Alderweireld to progress and round Hugo Lloris.
The Brazilian, however, stumbled at the final hurdle, lifting his shot over with Eric Dier desperately scrambling to cover on the line.
Carlo Ancelotti thrust back his head and covered his eyes,
The Everton manager, though, must have liked what he was seeing.
Seamus Coleman had twice snuffed out Heung-min Son in one-on-one situations, the Everton’s defender’s nous outweighing the Korean’s speed in both direct duels.
Everton’s football was fluid and direct.
Abdoulaye Doucoure stole in front on Son to prompt a raid which involved Coleman and James Rodriguez, feeding Richarlison for a strike deflected behind by Alderweireld.
Indeed, the lion’s share of Everton attacks were funnelled through James, who looked anything but a player without a competitive game for the best part of two months.
As for the Premier League’s renowned speed and physicality, they appeared right up the Colombian’s street.
He gave as good as he got in the tackle and gave Coleman sufficient protection on Everton’s right.
James, though, is not a social media phenomenon because he gets stuck in.
The 29-year-old does magical things with the ball at his feet.
Supplied by Doucoure after the Frenchman was alert to snaffle a second ball, James came close to adding to his library of exquisite goals eight minutes before half-time.
He despatched his shot in the blink of an eye but a fraction beyond Hugo Lloris’s left post.
James’ touch was less sure soon after the restart, screwing wide after Calvert-Lewin angled a low ball from the left.
Spurs keeper Lloris’s opposite number, meanwhile, made two critical interventions.
Harry Kane had been millimetres from connecting with a Son cross- the winger giving up trying to go on Coleman’s outside and sending in an inswinging delivery – when Pickford was confronted by Alli bearing down on goal.
Midfielder Alli, slipped in by Son, who intelligently held onto possession before passing, struck a rising drive which Pickford tipped over the top.
Pickford was equal to Matt Doherty’s 41st-minute effort, too.
Doherty continued his run after finding Kane and skipped onto a lofted return pass.
Pickford, however, stick out a right leg to deny the Spurs player a debut goal.
Everton, by and large, were defending soundly with Allan and Doucoure offering their back-four terrific protection.
And the away team had Spurs on the rack after half-time.
First came James’ opportunity, then the same player floated a cross from the right which Richarlison – who had drawn Lloris into a low save late in the opening 45 minutes – bundled wide at the far post.
There was no suspicion, though, of Everton letting their opponents off the hook.
Rather, Ancelotti’s team was turning the screw.
And when Richarlison was impeded by Alderweireld, Digne landed the resultant free-kick on the head of Calvert-Lewin for Everton’s breakthrough.
Richarlison thrashed a foot wide of the far post after yet another fine right-to-left pass from James and the anguished cries from Everton’s bench echoed around this ginormous ground.
The Everton forward again minutes later, progressing into the box, with Doherty keeping his distance, but missing in identical fashion.
Pickford twice punched clear as Tottenham began loading balls into Everton’s box and Alderweireld’s plaintive cries for a foul 20 yards from Everton’s goal fell on deaf ears.
Everyone lucky enough to be in Tottenham's swanky stadium, however, could hear multiple Everton shrieks of delight when Martin Atkinson blew for full-time.
DCL Steps Up
Dominic Calvert-Lewin made giant strides last season.
Claiming Everton’s number 9 shirt – at his own request – he responded to the task of delivering the goals that jersey demands.
He scored 15 in all competitions last term but, in his own opinion, should have had more.
Carlo Ancelotti is a confirmed fan – the player signed a new five-year contract within three months of the manager's appointment.
Calvert-Lewin’s hold up play has come on leaps and bounds. His decision making is excellent and he is proficient coming to the ball or running behind defences.
What Ancelotti wanted next was for Calvert-Lewin to become more clinical in the box.
The 23-year-old had played well here in the opening 55 minutes, got through an awful lot of important work, but not had a sight of goal.
That’s how it goes in the Premier League and explains Ancelotti’s demand.
How Calvert-Lewin responded.
Lucas Digne’s free-kick from the left was as good as it gets.
But Calvert-Lewin had a lot to get right.
He steamed into a pack of bodies, timing his run to the second, and got the jump on Eric Dier.
The header was exquisite, powerful and buried inside Hugo Lloris’s right post.
France’s World Cup winning goalkeeper didn’t have a hope.
Ancelotti and his staff erupted, haring from their seats.
Everton’s players converged in a corner where their supporters would normally have gathered, whooping and screeching and having a good go at creating the noise we’d have heard in normal circumstances.
Three And Easy
Carlo Ancelotti hinted he might take the plunge and play a couple of his new signings from the off here.
There was an element of surprise nevertheless when the Everton manger threw all three in at the deep end.
To watch Allan, James Rodriguez and Abdoulaye Doucoure, however, was to appreciate selecting the trio represented a straight forward choice for Everton’s manager.
James certainly validated his pre-match words about good footballers being capable of settling anywhere without fuss.
The Colombian’s slender frame belies a footballer who is strong and athletic.
Ben Davies for instance was alarmed to see James leap to his feet and show the defender a clean pair of heels after the Tottenham player’s initial heavy-handed challenge.
James connected with Lucas Digne on a number of occasions, one speared pass flat across the deck travelled 50 yards into the overlapping Frenchman’s feet.
There was a feint to give Dele Alli the slip and a strong arm to brush off Pierre-Emile Hojbjerg when the Spurs midfielder tried to rough up James after the whistle.
No suggestion either of James taking the safe option on debut for fear of a poor first impression.
The South American puts the ball at risk, tries things expecting the best and backs himself and his team to retrieve possession if required.
Allan bounded across the ground in front of Everton’s back-four. He intercepted, tackled and hassle opponents to distraction.
The Brazilian lived up to his reputation as much more than a win-it-and-give-it midfielder, too, the sort who does the grunt work, then passes to a more gifted teammate.
Allan passes the ball forward, capable of threading tight spaces or aiming more expansive passes for his attackers.
He was comfortable receiving possession when hemmed in by white shirts, manipulating the ball to create a passing option.
Doucoure, meanwhile, came to Everton vowing to add energy to the team’s football.
To prove the job of box-to-box midfielder isn’t completely passe.
He sprinted back towards his own goal like a man possessed early in the second half to dispossess Lucas Moura and ruin a dangerous Spurs counter.
Twice in the first half he was pivotal in Everton troubling Tottenham: once when stealing possession 25 yards from his own goal, again collecting a second ball deep in home territory.
James struck inches wide from the latter incident, while Doucoure’s toe in front of Heung-min Son prompted a surge which ended with Toby Alderweireld deflecting wide from Richarlison.
Doucoure is imposing, instantly adding presence to Everton’s engine room.
His leggy stride eats up ground and in possession he is unhurried and accurate.
Clean Slate, Clean Sheet
Everton recorded only one clean sheet in their closing seven games last term.
Whatever mitigating factors were at play, they are moot now.
This was a clean slate.
The new boys in Everton’s team will undoubtedly grab the headlines but shutting out Tottenham – whose attack is led by one of the world’s best strikers – required fantastic performances from more recognisable faces.
Seamus Coleman, on his 275th Everton appearance, defended immaculately, using his experience to suppress the usually electric Heung-min Son.
Coleman’s positioning to deny Son a clear run at goal in the opening half was tremendous. He galvanised and pressed and didn’t entirely abandon his attacking instincts.
The Irishman talked towards the end of last season in terms of Everton’s players fighting for parts in Carlo Ancelotti’s grand plan.
Coleman looked every inch a man for the future.
Yerry Mina, back from a muscle injury, won a succession of headers and defended intelligently.
The same goes for Michael Keane, who was instrumental in taming Harry Kane.
Indeed, the Tottenham striker didn’t have a shot on target.
When Spurs did find their range, they met their match in Jordan Pickford.
The goalkeeper, buoyed by successive clean sheets on international duty, didn’t put a foot wrong.
Saves at close quarters from Dele Alli and Matt Doherty were pure Pickford.
The 26-year-old commanded his box and twice enabled his defenders to heave huge sights of relief with haymaker punched clearances as Spurs went more direct in their hunt for an equaliser.
His booming shout of keeper and safe hands to claim Pierre-Emile Hojbjerg's high ball desperately tossed into the box deep into stoppage time was the work of a confident man.
