Gullit shouted Ousmane Dembélé's name in excitement, because this chance was simply too good.
It was not exactly an easy finish, but for a professional player, especially a forward playing for Barcelona, it was the kind of opportunity he could not afford to miss.
But Ousmane Dembélé missed it. Amid Gullit's excited shout, he used a textbook side-footed finish and sent the ball straight into Suárez.
At the crucial moment, he had actually aimed it wrong. After striking Suárez, the ball bounced back to Alisson, and Barcelona's golden chance right after kickoff came to nothing.
"Ousmane Dembélé failed to take this excellent chance. Barça were so close to opening the scoring against Liverpool!"
"How could you not be angry?"
"That pre-match interview with the Barça fan actually caused a major debate online. Some fans felt the supporter who criticized Ousmane Dembélé should have given the young player more confidence and more time."
"But does this Barcelona side really still have time?"
"When Busquets leaves, when Rakitic retires, when Alba gradually gets older, when Suárez gets older, when Messi's age keeps catching up with him, and Coutinho still can't find his form, will they still have a chance to reach the Champions League semifinals next season?"
"So they have no time left. Young players like Ousmane Dembélé have to step up now and carry Barcelona forward!"
The shot had not gone in, and Liverpool had also basically figured out Barcelona's attacking approach. They mainly created chances through movement in the final third.
The moment Messi carried the ball, Coutinho and Ousmane Dembélé would sprint at the same time, giving Messi three passing options: the two flanks, and Suárez through the middle.
For anyone else, it would be hard to get the ball out in such an isolated situation, but as long as Messi was given space, his passes could always create chances for his teammates.
So Liverpool's defensive focus shifted to limiting Barcelona's chances to keep possession.
Liverpool used the defensive tactic Zubizarreta was best at, denying Barcelona's forwards enough space to receive the ball.
Van Dijk was smart as well. He was now the one directing Liverpool's defensive setup at the back.
Van Dijk deliberately left Barcelona an area that looked close to the abdomen, but was actually nearer the upper abdomen, while focusing on protecting the lower abdomen.
That defensive pattern was exactly what made it so difficult for Suárez to find openings.
As a result, Barcelona naturally began working the flanks again, especially through Coutinho, who was actually playing quite well in this match.
Against Liverpool, he kept using his preferred passing style to create opportunities for Ousmane Dembélé.
But Liverpool's attack also began to click, especially through Leo Lin. Facing his former Spain teammate Busquets, he kept driving forward with the ball, preventing Busquets from leaving his defensive midfielder position.
With that, the only Barcelona midfielder left who could support the front line was Rakitic.
Whenever Leo Lin got past Busquets, he would immediately shift the ball left for Mané to attack Semedo.
Semedo, the Portuguese fullback starting this match, had been given high expectations by Barcelona fans.
But Semedo's recent form had also been deeply worrying. With him and Ousmane Dembélé responsible for Barcelona's right flank, that side could only be described as a mess.
In the 29th minute, Leo Lin tried to break through again. After getting past Busquets smoothly, Mané had already been waiting on the wing for a long time.
Klopp instinctively stretched out a hand, hoping Leo Lin would switch the ball quickly, but Leo Lin moved even faster than Klopp's gesture. Two seconds later, he had already played it to Mané.
Semedo had to face Mané's charge again. One was a winger in red-hot form, the other a fullback in poor form. When the two squared up on the flank, the result was obvious.
Mané suddenly accelerated, and Semedo could not keep up. In the next moment, Mané pulled farther and farther away from him.
But when Mané broke through to the byline, Semedo seized the chance and used the advantage of his long legs to try to intercept.
Mané instinctively feinted past Semedo, then rushed into the box, with Semedo still chasing from behind!
Lenglet also charged toward Mané!
But Lenglet's recent form had been poor too. Mané cut inside again, and this time he got past Lenglet as well!
The more Gullit watched, the more excited he became.
"Lenglet's been beaten too!"
"Shot!"
"Mané goes down!"
"Piqué and Lenglet knocked him over together!"
"The referee hasn't given the foul, and Leo Lin is furious!"
Leo Lin was more than furious. He chased after the referee and protested loudly. After Ter Stegen gathered the ball, the referee had no choice but to stop play, then showed a yellow card to Leo Lin, who was complaining wildly at him.
"Leo Lin has been booked for his angry protest!"
"The Liverpool players have surrounded the referee!"
"They're just as furious as Leo Lin. Mané is protesting too!"
The referee took a step back under Leo Lin's roar. At that moment, the linesman was frantically waving his flag, which meant he and the referee had different views of the incident.
Now it was Barcelona's turn to worry, and their players immediately rushed toward the linesman.
Klopp said nothing. He knew his words would not change the outcome, so all he needed to do was wait. But Leo Lin had to do this.
In truth, Leo Lin had not even seen how Mané was brought down. His attention had originally been on the right, thinking that if Mané passed the ball to him, he could slip it into the right channel for Salah to score.
While he was watching Salah's run, Mané was taken down.
So Leo Lin acted very convincingly. At one point, he even made the referee think he had seen everything, when in reality, he had seen nothing at all.
It was a very delicate foul, because Mané's leg collided with Piqué after the shot. The referee needed to determine whether Piqué had fouled Mané before he completed the shooting motion or after it.
That timing would decide whether it should be given as a penalty.
After the discussion, the referee returned to the pitch and made the gesture every Liverpool fan wanted to see.
"He points to the spot! Liverpool have a penalty, and Mané has won it!"
"After Lenglet was beaten, Piqué had to block Mané's shot, but his outstretched leg disrupted Mané's shooting motion and knocked him off balance!"
"The referee shows Piqué a yellow card!"
Leo Lin immediately returned to his warmer side. He followed the referee, trying to persuade him to take back the yellow card he had shown him, but cards like that were very hard to rescind.
Busquets suddenly walked over to Leo Lin.
"Leo, we're old teammates."
"Don't target me like this. Show me a little respect."
Leo Lin patted Busquets and laughed. "Then I'll deliberately miss this penalty. That should be enough respect for you, right?"
Busquets immediately nodded.
If Leo Lin really deliberately missed the penalty, that would absolutely be more than enough respect.
