Brazil opened the scoring soon, before 10 minutes, when Renan Lodi made a good start from the left and focused perfectly on the head of Lucas Paqueta, who finished off to the right of the Korean goalkeeper.
The canarinha continued to dominate the actions of the game but it was not until the 35 ’that he managed to score the second, with a foul goal by Coutinho, who put it from the front of the area through the right square of the goal of Jo. It was the first foul goal that the Brazilian team manages to score since Neymar scored against Colombia in September 2014.
Korea almost tied with a goal in Coutinho's own goal, which was to attempt a corner rejection after a confusing play inside the Brazilian area and sent the ball to Alison's post.
Brazil returned from rest with the same dominance and tranquility and took 15 minutes to expand to 3-0. It was with Danilo, who scored with a diagonal shot from the front of the area and entered as an unstoppable missile, through Jo's right-wing squad.
With the victory guaranteed, Tite made several changes. But he didn't put Rodrygo until 88 'and the young Real Madrid striker didn't have time to participate in any play.
