When the players from both sides returned to Camp Nou, everyone noticed that Pochettino and Valverde had made no personnel changes. Clearly, both managers intended to continue with their first-half lineups, though there might be some minor tactical adjustments.
With the whistle from Kuipers, Agüero tapped the ball back to Coutinho.
Almost instantly, Leeds United's front three pressed forward aggressively.
Milinkovic-Savic led the charge. He sprinted straight at Coutinho, and when the Brazilian passed back to center-back Lenglet, Milinkovic-Savic immediately shifted direction and closed him down.
Leeds United's attacking trio advanced step by step, and the midfield and defense pushed up behind them, collectively applying pressure and forcing Lenglet to pass back to the goalkeeper.
Milinkovic-Savic didn't hesitate, charging straight toward Cillessen and forcing the goalkeeper to clear the ball long.
The ball crossed the halfway line, but De Ligt judged it well, stepped forward, and outmuscled Felipe Anderson to head it back.
The two sides then fought for possession in the area between the halfway line and Barcelona's 30-meter zone.
"It's clear that Leeds United's tactics at the start of the second half are still aggressive. They're pressing high again, which is Pochettino's specialty."
"Despite leading 2-0, the Premier League champions obviously don't want Barcelona to control the tempo. They're fighting to maintain it themselves."
"The referee's whistle goes for a foul by Rúben Dias on Messi, but no card is shown."
"Leeds United's central defenders are incredibly young. Rúben Dias is only 21, De Ligt just 19, and even Militão, sitting on the bench, is only 20."
"This youth is one of Leeds United's biggest assets. They play with energy and intensity, and their high pressing in the first half completely disrupted Barcelona's rhythm. It played a crucial role in their dominance."
"But in the second half, did Valverde find a solution?"
As the commentator spoke, a gap appeared on Leeds United's right flank.
Arnold carried the ball up along the sideline, reached Barcelona's 30-meter zone, and suddenly switched play with a long pass.
The ball flew across most of the pitch, landing near the left corner of Barcelona's penalty area.
No one was marking that space.
Barcelona's defense reacted quickly, and Roberto rushed over immediately.
Robertson controlled the ball and passed it back to Bruno Fernandes without hesitation before surging forward.
The Portuguese midfielder understood instantly and chipped a lobbed pass behind the defense.
The pass was slightly overhit. Robertson caught up and managed to keep it in play, but his attempted cross struck the side netting.
"That attack didn't pose a threat, but Leeds United's entire sequence showed organization and creativity."
"Arnold's long diagonal was especially clever. When everyone thought he'd deliver into the box, he suddenly switched to the weak side. Brilliant thinking."
Soon after, Leeds United intercepted in midfield again. Kalvin Phillips cut off a pass and quickly fed Rodri, who relayed it to Bruno Fernandes and then to Milinkovic-Savic.
The Serbian midfielder received with his back to goal, turned to his right, and passed quickly to Dembélé. The young Frenchman drove down the right and crossed from near the byline.
Unfortunately, the cross carried too much pace.
"Leeds United are pressing very aggressively, while Barcelona are clearly struggling."
"Their midfield progression is stalling, and they can't find space to move forward."
"Leeds United, on the other hand, are building waves of attack. Barcelona must be cautious."
"Mbappé has dropped deeper to receive the ball with his back to goal."
"All three of Leeds United's attackers are rotating and dropping back frequently."
"Now Mbappé holds it on the left. Robertson is already overlapping, waiting for the pass."
"Mbappé doesn't release it yet. He dribbles forward, draws the defenders in, and then passes."
"Robertson collects it near the left edge of the box and sends in a cross toward Milinkovic-Savic."
"He controls it with his back to goal, spins, and shoots!"
"A beautiful move."
"Milinkovic-Savic's shot deflects off Lenglet and bounces out."
"Leeds United recover the loose ball. Another chance here."
"It's sent wide to Dembélé, who finds space down the flank. He drives to the byline and whips in a cross, aiming for Milinkovic-Savic again."
"It's headed clear, but Bruno Fernandes is waiting at the edge of the area. He goes for the volley!"
Gasps filled the Camp Nou.
Nearly 100,000 Barcelona fans held their breath.
Bruno Fernandes' strike was pure quality, but it flew just over the bar.
It was the 52nd minute. Since the start of the second half, Leeds United had relentlessly attacked, pinning Barcelona deep and dominating completely.
Barcelona hadn't managed a single entry into Leeds United's box, let alone a shot on target.
"Barcelona are in real trouble now. Leeds United's aggressive offensive structure is tearing them apart."
"Playing through Milinkovic-Savic in the middle has been incredibly effective."
"And Bruno Fernandes' long-range threat can't be ignored. He scored several goals like this last season. Barcelona need to protect the space in front of their box better."
"Vidal must track Bruno Fernandes more closely."
…
After around ten minutes of intense attacking, Leeds United began to ease off and regroup.
Barcelona gradually regained some possession and started to advance slowly.
That was normal.
The furious tempo at the start of the half had consumed a lot of energy.
If Leeds United didn't manage their stamina, they could tire too early and lose control later.
Even for a physically dominant side like Pochettino's, that level of exertion couldn't last forever.
Once Leeds slowed the pace, they consolidated their structure around the halfway line.
Barcelona stabilized through short passes, circulating the ball before attempting to push forward.
Near midfield, Busquets passed to Coutinho despite Milinkovic-Savic closing him down.
But Kalvin Phillips anticipated it, charging in from the side. Using his body, he nudged Coutinho aside and stole the ball cleanly.
Leeds United immediately counterattacked.
Phillips sent the ball ahead to Dembélé on the right. The winger chested it down, turned, and played it inside to Milinkovic-Savic.
Again, the Serbian positioned himself between Barcelona's defensive midfielder and center-backs. Lenglet stepped up, but Milinkovic-Savic shielded the ball with strength and composure. He waited until Arnold overlapped before releasing the pass to the right.
After laying it off, Milinkovic-Savic burst forward into the box.
Arnold dribbled into the right channel and whipped in a low cross toward him.
Milinkovic-Savic met it at the right edge of the penalty area, controlling it deftly with the outside of his foot before flicking it to Dembélé at the penalty spot.
Barcelona's defense had collapsed inward, shifting toward the middle and right side.
On the far side, Mbappé was unmarked near the left corner of the six-yard box, raising his hand for the pass.
But Dembélé couldn't find room to shoot. Shielding the ball from Busquets, he rolled it back to the edge of the box instead.
Bruno Fernandes was waiting, perfectly positioned. As soon as the ball reached him, he took one touch and drove it forward.
The strike flew through a gap between defenders, cutting across the penalty area before slamming into the bottom right corner of the goal.
Cillessen, distracted by Mbappé's movement and partially unsighted, didn't even see the shot coming.
Bruno Fernandes, who had nearly scored earlier, made no mistake this time.
"Goalllllllllllllllllll!"
"In the 58th minute, Bruno Fernandes scores again for Leeds United!"
"3-0!!!"
"Oh my god, what a sequence! Dembélé's back pass, and Bruno Fernandes hammers it home for Leeds United's third!"
"Barcelona's defense has completely fallen apart tonight, especially in midfield. Leeds United have destroyed their structure."
"Maybe Leeds United's passing isn't as intricate as Barcelona's, maybe their players are young, maybe they don't have world-class stars, but this group of young men have unleashed an attacking storm at Camp Nou."
"Just like last season, when they conquered the Bernabéu!"
"Perhaps we need to rethink our predictions for Group B. Maybe Leeds United are the biggest wildcard, and possibly the favorites to top the group."
"Based on their performance tonight at Camp Nou, we have every reason to expect more from these young players."
"3-0!"
"Valverde must act quickly now."
"Barcelona's performance tonight has been truly disappointing. They don't look like a team determined to challenge for the title."
"Their rhythm has been completely broken by Leeds United. The players have shown no urgency, no hunger, and no determination. Instead, they look lethargic and uninspired."
"That's Barcelona's biggest problem right now."
"In La Liga, they're winless in three consecutive games."
"Nearly 100,000 fans at Camp Nou are expressing their frustration by booing, furious at both Leeds United's dominance and their own team's lack of fight."
