Jens Castrov is one of the most talked-about figures ahead of this World Cup. Born to a German father and a mother from Naju, he proved his roots by choosing to play for the Korean national team despite being an orthodox midfielder who played for the German youth team. In particular, when it became known that his mother raised her son while emphasizing her identity as a Korean, the local community in Naju, Jeollanam-do gave him warm support, calling him 'Naju's only grandson.' Jens, who has a high level of activity and a versatile play style, was evaluated as a key resource to bring new vitality to the Korean national team's midfield, and the affection he showed for the Taegeuk mark after his international debut resonated greatly with fans.

However, the bar on the actual stage of the World Cup was high, and coach Hong Myung-bo pulled out an unexpected card in the first match against the Czech Republic. Contrary to the public's prediction that the aggressive Jens would start as the starter, coach Hong selected Lee Tae-seok as the left wingback considering defensive stability. This was the result of a tactical judgment that Lee Tae-seok's dedicated defense and fighting spirit were better suited to dealing with the Czech Republic's tall army than Jens' aggressive fighter nature. It was a moment for Jens to face the reality of tough competition for a starting spot, but it also meant that the tactical flexibility of the entire national team was further strengthened.

Lee Tae-seok, who started in the match against the Czech Republic, calmed concerns about himself with his ability. Despite his short stature of 174cm, he showed a strong fighting spirit and defended the left flank in aerial ball competitions with Czech players who were nearly 190cm tall. Not only was he good at physical combat, but he also played the role of opening the attack with sharp crosses and active overlapping, showing perfect performance in both offense and defense. Lee Tae-seok's 'strong' play was enough to gain the trust of coach Hong Myung-bo, and in the end, Korea was able to win 2-1 against the Czech Republic and earn three valuable points in the World Cup group stage.

Lee Tae-seok's performance is not only significant in that he contributed to the victory, but also in that he completed the record of 'father and son participating in the World Cup.' Following Cha Bum-geun and Cha Du-ri, he created a new page in Korean soccer history and recreated the fighting spirit of his father Lee Eul-yong with a modern sensibility. Of course, Jens Castrop is also sweating at the training ground with the same intensity as in real combat and is ready to go out at any time. Korea's left line, with Jens' versatility and Lee Tae-seok's tenacious defense, is expected to be a very difficult variable for opposing teams in the remaining World Cup journey, including the match against Mexico.
