While both sides exchanged attacks, making for a lively game, no goals were scored.

Of course, considering it was a final, sometimes one goal could decide the match, so this was quite normal.

After all, both goalkeepers were performing reasonably well.

In the 30th minute, Zhou Yi, just outside the penalty area, feigned a pass but then unleashed a sudden, low shot that zipped along the grass towards the bottom right corner of the goal.

Casillas, after a quick step, made a brilliant save, diving sideways and using his fingertips to push the ball out for a corner.

Dortmund won a corner kick on the right side of the goal.

Reus went to take the corner.

Seeing Dortmund get a corner opportunity, Klopp rose from his seat, walked to the sidelines, and focused intently on the field.

Center backs with height advantages like Hummels and Papastathopoulos crowded in front of Real Madrid's goal, ready to head the ball in for Dortmund.

Real Madrid's players also retreated almost entirely into their penalty area, defending the corner.

Zhou Yi didn't join the scrum, but waited outside the box as before. His task was twofold: first, to prevent a counterattack, and if the ball came his way, he could disrupt it slightly, buying time for his teammates to retreat. Second, of course, to be ready to pounce on any second ball and set up a second attack for his team.

Once the players were all in position, the referee Kuipers blew his whistle.

Reus ran up and kicked the ball into the penalty area.

The ball arced outwards, flying towards the penalty spot.

Players from both sides jumped up simultaneously to contest the ball.

In the end, Ramos, with his outstanding leaping ability, managed to head the ball before anyone else.

He was leaning backwards at the time, and using his core strength, he headed the ball out of the penalty area.

Ramos's header was quite powerful, and the ball flew high out of the box, landing in... Zhou Yi's area.

Seeing the ball flying towards him, Zhou Yi took a half-step back with his right leg, leaning his body back slightly to create space. As the ball arrived, he cushioned it with his right foot, not with much force, like tapping a ping-pong ball up.

The ball was cushioned by the inside of his right foot and flew back into Real Madrid's penalty area.

At this moment, the Real Madrid defense was busy pushing forward to play for offside, and Zhou Yi's touch sent the ball right into the space behind them.

The Real Madrid players still lingering in the Real Madrid penalty area reacted differently. Some stood their ground, raising their arms, knowing that whoever received the ball behind them would be offside.

Others retreated, looking up, ready to head the ball away again.

But they were still caught off guard.

At this point, goalkeeper Casillas chose to come off his line, deciding to extend his defensive range to fill the gap that the defenders hadn't been able to cover.

But he seemed to have misjudged the distance between the ball's landing point and the goal.

He had only just reached the halfway point when the ball began to drop to a headable height.

As the ball flew out of the penalty area, Hummels, who had already started to run out, suddenly saw Zhou Yi kick the ball back in. He quickly stopped running out and instead moved to the front of the goal, then jumped up before the unprepared Real Madrid players and flicked his head at the ball!

The ball didn't fly straight towards the goal, but had a slight arc, flying towards the goal in a parabolic trajectory…

Casillas had only just reached the edge of the six-yard box… He had run halfway, and discovering that the ball had been headed by the opponent, he paused for a moment on the edge of the six-yard box, and the ball passed over his head.

He then turned back in a hurry to chase the falling ball.

As the ball was about to cross the goal line, he threw himself back, reaching out to try to scoop the ball back before it went in.

But his reaction was still too slow…

The ball had already crossed the line when his hand knocked it back out, and the ball bounced off Mark's leg, who was following up, and back into the goal.

Casillas had already fallen into the goal, tangled in the net, and was powerless to do anything…

"Eh? Eh!! Goal!!" He Ping hesitated at first, then, seeing the ball fly back into the goal a second time, he roared with confidence. "Goal! Goal!! In the 31st minute of the match, Dortmund takes the lead!! Zhou Yi gets his first assist of the game! Of the last seven teams to score first in the Champions League final, only Bayern Munich in 2012 and 2013 failed to win the title. Of the last thirty-six teams to score first in the Champions League final, thirty ultimately won the championship! Now Dortmund has taken the lead in the Champions League final!"

"Toooooooooooooooooor!!!!" Marcel Reif was also excited. "Was it Hummels or Mark? But regardless, the ball is in, Dortmund leads Real Madrid by one goal in the final! Oh! The subtitles say it's Hummels who scored! This is the first defender to score in a Champions League final since Sol Campbell and Beletti in the 2006 Champions League final!"

Compared to the excitement of the Chinese and German commentators, the Spanish commentator's disappointment was evident: "This goal conceded… Sigh!" He sighed heavily. "Dortmund launched an unexpected attack, and Hummels's clever header helped them take the lead. Real Madrid made a series of mistakes in this defense!"

After scoring, Hummels double-checked, immediately turning to look at the linesman. If the linesman was standing still, it meant there was a problem with the goal.

But he saw the linesman running towards the halfway line!

As a seasoned professional player, how could he not know what this meant?

The goal stood!

Yes, the goal was good!

Referee Kuipers also blew his whistle, turned, and pointed towards the center circle.

He excitedly ran towards the corner flag, then performed a sliding knee, falling to the ground.

His teammates followed suit, sliding on their knees and then pouncing on him, celebrating the goal with excitement.

Dortmund fans in the stands jumped and cheered.

The television broadcast then cut to Casillas, who freed himself from the net and kicked the nearby ball away before placing his hands on his hips and looking up at the sky, looking very dejected.

The broadcast then replayed the goal, showing the entire process from Reus's corner kick to the ball flying into the goal, with different angles providing a clear view for everyone.

"...Casillas made a series of mistakes in this defense. First, he shouldn't have rushed off his line when his defenders were still in position. Second, he misjudged the landing point of Zhou Yi's chipped ball. The third mistake was his sudden slowdown and hesitation halfway through his run, which allowed Hummels to easily complete the header. The fourth mistake was his momentary hesitation when the ball flew over his head, his reaction was half a beat too slow... In short, this goal was caused by a series of errors by the goalkeeper..."

"For this kind of ball, the goalkeeper should either stay on his line and let his defenders defend it, even if the defenders don't reach the ball, they can still interfere with the player, and then the goalkeeper makes a save in front of the goal. If he wants to come out, he has to be decisive and resolute, coming out and diving, even if he doesn't get to the ball, he has to interfere with the opponent's player. But Casillas came out halfway and then stopped, which is fatal..."

"Perhaps Casillas didn't expect that he would misjudge the landing point of the ball. When he realized that the landing point was different from what he expected, he panicked... This situation is very rare for Casillas in the past. But it happened in such an important match like the Champions League final... I can only say that it is indeed difficult for a goalkeeper who has only played twenty-three games throughout the season to maintain good form, especially in the past twenty days, Casillas has only played two games..."

"Real Madrid paid the price for their internal struggles. As the main goalkeeper in the Champions League, Casillas did not get enough match practice, and Casillas clearly showed unfamiliarity in judging this high ball..."

"Casillas's physical fitness is declining rapidly, coupled with the lack of games, his problems in catching high balls have been magnified—he originally had shortcomings in this area, but he could still make up for it with his excellent jumping ability and reaction. But now, with age increasing, his jumping ability has declined, coupled with the lack of games and insufficient state accumulation... which ultimately led to the mistake on this ball..."

"There is nothing to say, this goal is Casillas's responsibility. This was not a very good opportunity for Dortmund, but it eventually turned into a goal..."

Commentators from various countries turned their attention to Casillas.

The former Real Madrid legend, the captain of Real Madrid, "Saint Iker," had saved Real Madrid's fate time and time again. No matter how fierce the enemy's attacks were, he would not surrender or give up.

But this time, after looking up at the sky, he lowered his head deeply.

He blamed himself.

But this was not his sole responsibility.

The television broadcast then cut to a close-up of Real Madrid President Florentino watching the game in the presidential box.

The helmsman of the Galácticos showed no expression.

The broadcast then scanned to Real Madrid coach Ancelotti.

In any case, the decision to let Casillas play in the cup matches and Diego López play in the league matches could not have been made by Florentino. As the head coach, Ancelotti must also bear the corresponding responsibility.
