The Czech Republic was heavily tipped for defeat in the round of 16 against the Netherlands.
The Netherlands with three straight victories in the group stage would "just move on".
But the Netherlands put themselves in a difficult position when defender Matthis De Ligt was sent off in the 55th minute.
De Ligt took the ball by hand as the last man in the defense, and after a VAR review, he received a red card and had to leave the field.
The Czech superiority used the numerical superiority mercilessly.
