The coaches arrived one after another after receiving Klopp's call.

When they pushed open the office door and found Zhou Yi inside, they were all taken aback.

But it was only for a moment. They quickly greeted Zhou Yi as if nothing had happened.

Zhou Yi returned their greetings one by one.

With both sides in the same room, no one felt anything was amiss.

This wasn't the first time they had done this.

Once everyone had arrived, Klopp pointed to Zhou Yi and said to them, "Regarding our upcoming match against Atlético Madrid, Zhou Yi has an idea he wants to share with you all."

Zhou Yi didn't decline. He stood up and explained to the other coaches the ideas he had shared with Klopp.

After everyone had listened to him, the office fell into silence. Everyone lowered their heads, deep in thought, considering whether Zhou Yi's idea was feasible.

Klopp didn't rush them, but waited quietly by the side.

Soon, Željko Buvač, one of the assistant coaches, was the first to express his opinion: "I think it's feasible. And Atlético Madrid certainly won't expect us to use this method to deal with them. This can also serve as a secret weapon to catch them off guard."

"It's theoretically possible..." Teddy de Beer said with some uncertainty. "But doing this will be very physically demanding..."

"Of course," Zhou Yi nodded. "We should be constantly in this fast-paced state for a period of time."

"Then our physical fitness..." De Beer turned to look at the fitness coach, Oliver Bartlett.

"Just for this one game, it's not a problem. But for the weekend league match, we'll have to rotate the squad significantly," Bartlett offered his opinion.

"Our opponents for the weekend league match are Bayer Leverkusen, who are currently ranked fourth," said Peter Krawietz, who was responsible for collecting information on opponents. He naturally had to be well-versed in the situation of each opponent, and this information came readily to him. "They have fifty-four points, four points less than Schalke 04 in third place, but only one point ahead of Wolfsburg in fifth place. It will be their home game, so they won't let us off easily..."

"That's a problem," De Beer frowned after hearing Krawietz's words. This situation meant that Dortmund had to go all out in the weekend league match, otherwise they might lose to Bayer Leverkusen away from home, and the league lead they had obtained would be handed over again.

Everyone had basically expressed their opinions. They all turned to look at the head coach, Klopp. In this team, the final decision still rested with the head coach.

Klopp listened to the coaches' opinions and fell into deep thought.

After a long while, he looked up: "I know it's difficult, but when the season gets to this point, there are no easy games. If we don't want anything else, just a Champions League qualification for next season, it wouldn't be so difficult. We can give up the Champions League, making it to the semi-finals is already amazing. We can also give the league title to Bayern Munich, anyway, our second place in the league is already guaranteed... But if we do that, I know you certainly won't agree... We've worked hard for a season, not to surrender at the last moment, right, everyone?"

Klopp's coaching staff laughed.

"Of course!"

"So, despite the many difficulties, I want to try it, or rather, take a gamble. Let's do it according to Zhou Yi's idea. I need everyone to work closely together."

Dr. Braun, the head of the medical team, stated: "I suggest that we can appropriately increase the number of physiotherapy sessions, and arrange for everyone to take cold baths after training to speed up the body's recovery."

Klopp nodded in agreement: "You are the head of the medical team, you arrange these things, Doctor."

Dr. Braun turned to Zhou Yi and smiled: "In that case, Zhou Yi, the time you spend alone with Katharina will be greatly reduced..."

Everyone in the room laughed.

Everyone liked to joke about Zhou Yi and Katharina, also because they were popular.

Amidst the laughter, Zhou Yi scratched his head: "It's okay, as long as we can win the championship, this little sacrifice is nothing."

Klopp clapped his hands loudly and said, "Very good, everyone knows what they should do. Let's start preparing now! We don't have much time left!"

When Zhou Yi took his leave, the other coaches were still in Klopp's office.

Klopp then told them the story of how he gave the USB drive to Zhou Yi.

"One night... truly remarkable..." Teddy de Beer said with emotion.

"Not one night, he started thinking about it from the moment he saw the game..." Peter Krawietz said.

"That's also remarkable. Zhou Yi is truly the most unique player I've ever seen," De Beer said. "I'm 100% sure that Zhou Yi can become a coach after he retires, and he will become a very successful and excellent coach."

"I didn't really have much hope at the time, but Zhou Yi gave me a surprise," Klopp said. "I only have one regret now... I should have given him the USB drive immediately after our game against Mainz, so we would have had one more day to prepare."

"It's not bad now, it's better than you not showing him the USB drive at all, right?" Buvač joked. "You came up with this idea on the spur of the moment. How many coaches would think of letting their players watch this kind of thing?"

When the team's training session began, the players found that the training content was different from usual.

The training content in the "footbonaut" small black room was increased.

In addition, one-touch passing and receiving practice in a small-range confrontation state was also increased. It was required that all players must pass with one touch in a ten-meter by ten-meter area, and also had to be carried out under the interference of defending players.

In addition, the content of physical training was also increased accordingly.

Apart from these, there was no other training content all day long.

After the training, each player had to take a cold bath, and then go to the physiotherapy room to queue up for physiotherapy to relax their muscles and eliminate fatigue.

Although the coaching staff did not explain why they were doing this, everyone was not stupid and knew that this was definitely for Atlético Madrid.

At the same time, the training was closed to the public, and no media reporters or fans were allowed to approach Dortmund's first-team training ground.

The tense atmosphere of the upcoming big game began to gradually spread.

The media were of course very dissatisfied with Dortmund's closed-door training policy. Except for a small number of Dortmund local media and Chinese media who expressed their support, other media bombarded Klopp's approach.

"Cowardly, timid, afraid to face the challenge!" This was the title of Bild's article, and it was of course talking about Klopp. They believed that Klopp's approach fully demonstrated how fearful he was in his heart, because only those who had no confidence in themselves and had no confidence would choose to hide themselves, thinking that this would make their opponents helpless.

Kicker also believed that Klopp was exacerbating the tense atmosphere and was completely unhelpful to the team's performance. Closed training was the worst of all options. "...Klopp is tantamount to implying to his players that he has no confidence in winning the game, otherwise why would he hide and cover up? This approach can only make Dortmund's players lack confidence and morale. If there was still a chance to fight, now I'm afraid they can only admit defeat..."

The Munich media even used the most sarcastic language against Dortmund and Klopp, taking the opportunity to vent all their resentment for being overturned by Dortmund in the league.

"...If I were Klopp, I would give up the Champions League. Why suffer so much? Does he really think that being one point ahead in the league can guarantee that Dortmund will win the league title?"

"After Dortmund defeated Bayern Munich at the Allianz Arena, they are now putting themselves on the shelf to bake. Atlético Madrid is not an easy opponent to deal with, and Bayer Leverkusen in the next round of the league will also fight Dortmund desperately to ensure the top four in the league. Playing on two fronts is a torment for Dortmund, who are full of injuries this season, and may even end up empty-handed, gaining nothing in either the Champions League or the league!"

……

So how did Klopp and Dortmund respond to these comments in the media?

They did not respond in any way. Neither Klopp nor the players accepted interviews with reporters, and did not make any explanation for their actions.

Of course, this attitude was naturally regarded by the media as a manifestation of guilt. The more they dared not speak, the more panicked they were in their hearts.

When the news that Klopp strictly prohibited players from accepting interviews with reporters was exposed, it further confirmed this speculation by the media.

Because of the closed training, no one knew what Dortmund was doing, but that was not important. With only three days of training, even if they were tinkering with some secret weapon that had never been exposed before, what effect could it have?

There are always objective laws to pay attention to. No team has ever been able to learn a completely new tactical style in three days.

So what Dortmund is doing behind closed doors is not important at all, and no one cares about it. Everyone is just seizing this opportunity to ridicule and criticize Dortmund...

These overwhelming reports from the media also affected fans in China. Many people also thought that Klopp's approach was too stupid - closed training is a stinky trick in Chinese football. Even Chinese football, which is not very good, has not done this for a long time. I didn't expect that the dross of Chinese football would be picked up by Klopp. Could it be because he has two Chinese players in his team, so Klopp naturally thinks that this will be effective?

"Didn't Zhou Yi and Yan Min explain the idiom 'closing the door to build a car' to Klopp?"

A famous online football V issued such a question on Weibo.
