Why is the training of national football different from that of Korean men's football?

The South Korean team is practicing more offensive routines. A leak in the front tip and a shot in the back heel. The originality of technical drills. It can be called a shining future. China has no such routine. More is a single style of play, activities are on the sidelines, so they are all elite players in the league, such as Mao Jianqing of Shenhua and Feng of Shenlongyuan. Wang Zheng Luneng. Breakthrough is the best. From winger to winger. Infiltration is also a means of attack. That's why players like Conca are arranged. The ball is strong, so the offensive means are diverse. Controlling the midfield may not shock the whole situation. There is no doubt that Korean players can occupy a place in the AFC Champions League and K League, calling themselves the AFC Champions League. The diversity of football is a new field of traditional football. So why can Korean players and Japanese players see them in the World Cup? More overseas players have been trained. That's the point.
