Thomas Delaney’s header and Kasper Dolberg’s volley in the first half put Denmark in control of Saturday’s quarterfinal.
The Czechs were a different side after the interval and Patrik Schick’s clever finish — his fifth goal of Euro 2020 — ensured Denmark had to work for its 2-1 victory.
It looked unlikely after defeats to Finland and Belgium in its first two group stage games, but the 4-1 hammering of Russia and Finland’s 2-0 defeat to Belgium secured its place in the last-16.
The Danes then secured a hugely impressive 4-0 win against Wales to announce its arrival in the latter stages of Euro 2020.
Denmark’s players spoke of the emotional toll returning to finish the game of Eriksen’s collapse the same afternoon had on them, with several members of the squad criticizing European football governing body UEFA for not allowing them to play the match the following day.
Given this group’s remarkable mental fortitude, Denmark fans may have perhaps already allowed themselves to start dreaming of a repeat of Euro ’92, when the national team secured its only major international trophy to date.
