1. Unstable defense
South Korea again exposed their weakness, which is unsolid defense. Korea’s head coach Shin Tae-yong played with three defenders at the back to overcome this, but it did not worked out well yet.
With this formation, Korea held a numerical advantage in a defensive situation, but that was it. Three defenders were not organised and did not seem to communicate with each other well enough, leading to frequent mistakes. Korea’s central defender Hong Jeong-ho especially missed the ball in the 35th minute and right before the final whistle, which allowed a good opportunity for Poland to make a counter attack.
It didn’t take long for Shin to realise a 3-4-3 formation was not right for the team. He gave up a 3-4-3 formation by replacing Kim Min-jae with another forward, Hwang Hee-chan.
