Klinsmann trained at Paju NFC on the 10th ahead of the friendly match against Tunisia (Seoul) on the 13th and Vietnam (Suwon) on the 17th. On this day's training, all 24 players, including overseas players such as Son Heung-min (Tottenham) and Hwang Hee-chan (Wolverhampton), came to the ground in full form.

This training was conducted as 'Powerade Fan Open Training' and was held in front of 300 fans recruited on a first-come, first-served basis. An official from the Korea Football Association (KFA) expressed enthusiasm, saying, “As soon as we started recruiting, 300 people filled up immediately.”

Fans watched the players up close with witty phrases such as “Congratulations Lee Kang-in on your discharge,” “Seol Young-woo is a prince,” and “Heung-min, don’t get sick and get married late.”

As the players appeared and began to warm up, fans cheered and shouted the names of Lee Kang-in (PSG), Son Heung-min (Tottenham), Seol Young-woo (Ulsan), etc., and the atmosphere at the training ground was as hot as a stadium where an international match was being held.

After full-scale training began, the players were unable to be close to the fans because they were concentrating on training, but Son Heung-min showed good sense.

Son Heung-min, who was excluded from team training that day and did personal training such as cycling and jogging, moved right in front of the stand where fans were gathered and jogged, and whenever fans called his name, he waved his hand or responded with a 'hand heart' to the fans. It gave me joy.

After completing training for about 1 hour and 10 minutes, the players took a group photo in front of the fans, and all 24 players signed an autographed white tiger doll as a gift to the fans through a drawing. Seol Young-woo, Son Heung-min, Jung Woo-young (Stuttgart), and Oh Hyun-gyu (Celtic) were present at the drawing ceremony.

The national team players, who met with domestic fans four months after the two-game international match in June, looked bright as they received support from the fans.

Cho Kyu-seong smiled brightly, saying, "(Playing on stage in Denmark), I was happy to see only Asians in the stadium. This time, I am even more grateful and happy to meet our fans." Hwang Hee-chan also said, “Time with fans is always precious.”
