After the game, the team had a simple relaxation session.

Jurgen Klopp, the head coach of the team, announced that this is the end of today's training, and the players can go home on their own after rinsing up.

As for Li Shuai, Klopp didn't say much, but just told him to attend training on time tomorrow.

Li Shuai has only played for about 20 minutes and has just entered the state, which makes him a little unsatisfied.

If you want to practice, when you first arrive at Dortmund, you are not familiar with life, unlike at Manchester United, where Pogba and Lingard cooperate.

However, looking at Hummels and Grosskreutz beside him, Li Shuai quickly had an idea.

Li Shuai didn't have any surprise to the two teammates who took the lead in expressing friendship to him, and grabbed Hummels and asked, "Mats, I heard that the team has a training room called Footbonaut?" ”

This is an interesting thing that Li Shuai found when he learned that he would be loaning to Dortmund, and he looked up the team information on the Internet.

If the real situation is consistent with the information on the Internet, with this thing, he doesn't need teammates, he can practice by himself.

Before Hummels could speak, Grosskreutz beside him spoke first: "Want to try?" ”

"I want to try it, it's only been playing for a while, and my body hasn't moved yet!" Li Shuai smiled and said.

Grosskreutz saw that his new teammates were so motivated, and laughed and said, "Let's go, I'll show you there, that's a good thing!" ”

After speaking, Grosskreutz, who had a straightforward personality, pulled Li Shuai and left.

Hummels didn't speak, just looked at the two of them with great interest, shook his head, and followed quickly.

…………

In a corner of the club's training center, Grosskreutz pointed to a square, about 200 square meters white house, and said to Li Shuai next to him: "This is what you call the 'Footbonaut' training room."

"This is it, this unsightly house?"

According to information on the Internet, the cost of this house reached 1 million euros, which is equivalent to nearly 10 million RMB.

"That's it?"

However, after entering, Li Shuai soon found that there was a lot of things inside, there was a cage in the house, and there was an artificial turf in the cage, and there was a circle marked by a white line in the artificial turf, just like the center circle of the court.

There was a lot of light shining into the cage above the roof, and in the dark room without windows, the cage was as bright as day.

Hummels told Li Shuai that the house is made up of 72 specially made wall panels on all four sides, and each wall has two ball machines at the top and bottom, one close to the ground and one much higher.

And the workflow of this training room is not complicated, the control center of the training room first gives a sound signal for the kick-off, and then one of the 72 wall panels on the four walls will light up immediately, and the ball will shoot out of this wall panel.

A few seconds after the player standing in the center of the room receives the ball, a wall board will light up in an unknown direction, and the player will kick the ball to the corresponding position, which is based on a set of response actions of the visual nerve center.

The number of catches in a session, the speed and height of the serve, and the difficulty of the pass can be set in the background, and then the player needs to respond to the incoming ball with corresponding technique.

It is worth mentioning that the spin of the ball will change when it is shot, and the top speed can even reach 120 kilometers per hour!

Through the "footbonaut" training, the players' reflexes can be exercised to adapt to the 360° incoming ball, and at the same time, the players can be trained to receive, stop and pass the ball efficiently.

Hummels made an introduction, and Grosskreutz had already set up the program, entered the iron cage, and began to demonstrate it to Li Shuai himself.

During the Grosskreutz demonstration, Hummels continued to introduce Li Shuai.

According to him, the operation of the training room is very simple, the control center is made up of a single tablet, and all the player test data is quickly recorded and then transmitted to the coach.

The training room can even be completely unmanned, where players can test and train on their own, where they can test and train what would otherwise require multiple coaches.

For the team's tactics of emphasizing one-kick and pressing attack, this training room is very targeted, so that every player in the team has a high level of foot handling ability and reaction speed on the court.

In addition, this "footbonaut" training room can not only do passing training, but also shooting training, goalkeeper training, and not only single training, but also can accommodate multiple people for cooperation training.

Li Shuai listened to Hummels's introduction and observed Grosskreutz in the iron cage, and Li Shuai found that in less than 20 minutes, Grosskreutz made about 200 touches of the ball.

However, it can really exercise the basic skills of the players, and can also improve the relevant awareness, preparation and judgment of the players.

"Very efficient and applicable!" This is Li Shuai's evaluation of "footbonaut", which is indeed valuable.

After less than twenty minutes of training in the "footbonaut", Grosskreutz was already sweating profusely.

Li Shuai is quite clear about this situation, in fact, an ordinary player will be very difficult to complete 15 consecutive passes and receptions in the non-stop receiving, passing, and turning (turning), let alone nearly 20 minutes.

This training, to a certain extent, can be described as killing multiple birds with one stone, not only tempering the player's skills, but also achieving the effect of physical training.

Seeing Grosskreutz come out, Li Shuai was already eager to try it and couldn't wait to experience this "high-tech".

Grosskreutz looked at Li Shuai like this, and suddenly said with a wicked smile: "Just now, in order to show you, I only set the ball speed to a speed of 50 kilometers per hour, and I usually use 80, how much do you need to set?" ”

This guy really has a straightforward personality, and with such an obvious expression on his face, he has betrayed himself.

Li Shuai understood almost instantly, "There must be a conspiracy!" It's just that he didn't break it either.

Unexpectedly, this guy didn't open his mouth when he saw Li Shuai, and actually added: "I don't believe you ask Matz, I usually use a speed of 80." ”

What's even more interesting is that the guy said while winking at Hummels as if no one was around.

What can Li Shuai say, there are only two words: "I serve!" ”

Hummels looked at his friend's poor acting skills and couldn't bear to look at him and said, "I'm using 80 speeds." ”

Hummels's words made Li Shuai pause.

What exactly is the concept of speed 80?

On the general court, the passing speed is about 50-60 kilometers per hour, which is already a very good ball speed.

In short, passing with a speed of more than 80 is rare on the football field, and a speed of 80 and 100 is also a great challenge for top players, and their passing success rate can only be maintained at about 6 or 7 percent.

Although Hummels indirectly exposed Grosskreutz's lies, he also showed his strength.

However, since Hummels can complete it, Li Shuai, who has never stopped basic practice, believes that he will not be bad, and walked into the iron cage and directly asked Grosskreutz to set the ball speed to 80.

Hearing Li Shuai's words, Grosskreutz didn't mind Hummels' demolition, and looked like he had succeeded in his treacherous plan, and said with a smile: "It'll be right away." ”

Immediately, Li Shuai heard the sound of "da", "da", and "da".

Having seen Grosskreutz's demo, Li Shuai knew that it was a countdown.

After that, the seventy-two special wall panels in the cage suddenly lit up red at the same time.

Then, one second later, the red light turns yellow, and another second later, the yellow light turns green.

After the green light went out, Li Shuai held his breath and condensed, knowing that this was the ball machine placed around him, and he was about to start playing.

Just listen to "beep ~ beep!" "Twice.

In a ball machine with a red glow near the ground, a football suddenly flew out at a speed of 80 kilometers per hour towards the middle circle where Li Shuai was.

"What a speed!"
