Who plays in the World Cup today is the main question as the round of 16 begins Saturday with knockout games that put the United States against Belgium and Spain against Portugal. The bracket moves into elimination soccer, and the first results will tell which teams can build on rare or first-ever knockout wins.
United States and Belgium
The United States reaches Monday night in Seattle after its first knockout-round win since 2002, a step that puts Belgium in front of a team that already pushed through a long wait to get here. Belgium needed a miracle victory over Senegal to stay in the tournament, so this matchup brings two sides in with pressure already attached.
That meeting also carries a recent reference point. In 2014, the United States and Belgium played a scoreless match into extra time before Belgium won 2-1, which gives Monday night a direct comparison without changing the stakes now. The same matchup now sits inside the round of 16, where one mistake sends a team home.
Spain and Portugal
Spain and Portugal is the other headline pairing, and Cristiano Ronaldo is part of the thread running through it. At 41, he scored the equalizer in the 88th minute when Spain and Portugal played to a 3-3 draw in the 2018 prelims, and Portugal beat Croatia with Ronaldo's penalty kick.
Spain enters without having conceded a goal in the tournament, and Unai Simon set the Cup record for scoreless minutes at 519 dating from 2022. That combination is unusual in a knockout bracket: one side has not been breached, while the other has a forward who has already forced late answers in this rivalry.
Rare wins across the bracket
Several other teams arrive with fresh knockout history. Spain and Paraguay won a knockout round for the first time since 2010, Norway did it for the first time since 1998, and Switzerland did it for the first time since 1938. Canada and Egypt also won a knockout round for the first time ever.
The schedule adds more weight to the day. England will play Mexico at Estadio Azteca in Mexico City, France will play Germany in the tournament, Brazil will play Norway on Sunday, and Morocco is expected to play Canada on Saturday. Brazil took out Japan five minutes into stoppage time, and Erling Haaland supplied the winner against Ivory Coast four minutes from the end of regulation, so the field is full of teams that needed late breaks to stay alive.
Argentina, the reigning champion and the planet's top-rated team, was taken deep into extra time by 67th-ranked Cape Verde before winning on an own goal after extra time on Friday night. That result keeps the bracket unsettled as the round of 16 starts, and it leaves one basic answer for fans checking the schedule: the first day is about who survives, not who looks safest on paper.
