The first quarter-finals match of the day will see Croatia take on Brazil at Education City Stadium.
Brazil are going into the match with confidence after a 4-1 win against South Korea.
Croatia's last round of 16 match with Japan saw them win 3-1 on penalties.
Brazil are undefeated against Croatia in their last four matches. If Croatia wins tonight, though, they will be entering their third semi-finals. They finished third in 1998 and were runners-up in 2018.
Meanwhile, Croatia have only conceded two goals, in the tournament so far. However, they will be facing the most successful team in international football history, as Brazil have been in the semi-finals for an impressive nine times and if they win the tournament this year, it will be their sixth World Cup title.
Match kick-off is at 6:00 pm Doha time.
Croatia line-up: Livakovic; Juranovic, Lovren, Gvardiol, Sosa; Modric, Brozovic, Kovacic; Kramaric, Pasalic, Perisic
Brazil line-up: Alisson; Militao, Marquinhos, Thiago Silva, Danilo; Paqueta, Casemiro; Raphinha, Neymar, Vinicius Jr; Richarlison
