he 24 players who were called up in preparation for the October international match sweated on the ground for about an hour under the guidance of Coach Klinsmann and Coach Cha.

On this day's training, Coach Cha had to take on the role of head coach Andreas Herzog. This is because Head Coach Herzog returned home in a hurry due to his mother's health deteriorating.

Although it was an 'open training' held in front of 300 fans, Coach Cha shouted and instructed the players.

Among the players who completed the warm-up together, Son Heung-min, Cho Kyu-sung (Midtjylland), and Park Yong-woo (Al Ain) did not participate in the training due to condition management.

While Jo Hyun-woo (Ulsan) also worked hard with his goalkeeper coach, the main training part was a mini game in which the remaining 20 players were divided 10 to 10 and only used half the ground.

In this training, Coach Cha showed great chemistry with Coach Klinsmann

In particular, Coach Cha, who is fluent in foreign languages, immediately translated Coach Klinsmann's instructions into Korean.

When Coach Klinsmann gave instructions softly, Coach Cha would shout loudly so that the players spread out across the field could understand them.

When he didn't like the play of the players in front of him, he encouraged them by pushing them hard.

He also took on the role of directing detailed movements to ensure that the head coach's 'philosophy' permeates the players' movements.

Coach Cha ran around the ground with the players who were pressing forward, loudly reminding them, "You don't just steal it! The goal is to steal it and then keep the ball!"

It was a scene that revealed his player coaching skills, which he honed while working as the coach of the K League 1 FC Seoul Under-18 (U-18) team, Osan High School.

Coach Cha originally joined Klinsmann in the position of national team 'advisor' rather than coach.

Coach Klinsmann served as a technical advisor at the time of the launch to ensure a soft landing for the Korean national team. Last month, after parting ways with existing coach Michael Kim (Korean name Kim Young-min), the national team appointed Coach Cha as 'coach'.

Son Heung-min, who focused on stretching away from the main base, did not join until the mini-game was over.

Previously, Coach Klinsmann announced at a press conference on the 9th that he would manage the condition of overseas players, including Son Heung-min, by controlling their training volume.

Meanwhile, unlike Son Heung-min and Cho Kyu-sung, Kim Min-jae (Bayern Munich), who joined immediately after playing his team's game in the early morning of the 9th, trained normally.

Fans who attended the national team training that day gave strength to the players with witty cheering slogans.

Lee Kang-in (Paris Saint-Germain), who won a gold medal at the Hangzhou Asian Games and received the benefit of serving as an art and sports agent, shouted, 'Congratulations on Lee Kang-in's discharge.'

Jo Kyu-sung, who was fluttering his long hair, made people laugh with the slogan, ‘Cho Kyu-sung, cut your hair.’

Hwang Hee-chan, who met with reporters before training and said, "I look forward to new cheering slogans from fans," mentioned actor Yeo Jin-goo, who is considered a celebrity lookalike, and shouted, "Why does Yeo Jin-goo play soccer!", making Hwang Hee-chan laugh.
