Croatia defeats Brazil 1-1 (penalties: 4-2) in quarterfinals
Brazil entered the quarterfinal matchup as a heavy favorite over Croatia, despite the Vatreni reaching the 2018 World Cup Final. Neymar and co. were stunned after scoring the first goal of the game in extra time after a goalless 90 minutes. After an impressive equalizer from Croatia's striker Bruno Petković, it was penalty shoot-out hero Dominik Livakovic who lifted the Vatreni into the semifinal. The Croatians now head to the semifinals for the second straight World Cup after their 2018 tournament ended in a loss to France in the final.
