Flamengo will play their first match in the semi-finals on 7 February and Real Madrid a day later.
The tournament will see further experimentation in the Video Assistant Referee system as referees will explain the reasons for VAR decisions to stadium crowds and television viewers for the first time.
During the test, the referees will broadcast their decisions via a microphone connected to the public address system, although their interactions with the video officials will remain private.
The tournament in Morocco is one of the last with the current format as FIFA has announced that they will host an expanded Club World Cup with 32 teams in mid-2025.
