The inaugural expanded Club World Cup has handed over a spectacle on the pitch, with underdog triumphs and captivating support from South American and Arabic fans.
However, concerns over player welfare and lukewarm attendances in the United States have sparked debate as the tournament approaches its final stages.
What many anticipated to be a European-dominated affair has instead seen shock eliminations of UEFA Champions League heavyweights.
Brazilian sides Flamengo, Botafogo, and Fluminense, alongside Saudi Arabia's Al Hilal, have scripted some of the tournament's most thrilling stories.
Fluminense stunned Inter Milan with a 2-0 win in the Round of 16, while Al Hilal handed over a seismic upset by knocking out Pep Guardiola's Manchester City.
Lionel Messi's Inter Miami also played their part earlier in the tournament, defeating Porto 2-1 in the group stage - ending a 13-year unbeaten run for European teams against clubs from other continents in the competition.
Meanwhile, Botafogo and Flamengo claimed memorable group-stage victories over Paris St Germain and Chelsea respectively, while Palmeiras secured their quarter-final berth with a dramatic extra-time win over Botafogo in an all-Brazilian clash.
Extreme weatherWhile the on-field action has enthralled the fans, challenges off the pitch have raised eyebrows.
The American summer's extreme weather — scorching heat and unexpected thunderstorms — has disrupted matches and raised serious concerns ahead of the 2026 World Cup, which will also be gripped in North America.
The soaring temperatures and oppressive humidity have fueled major complaints from players and coaches and have global players' union FIFPRO is exploring whether extending halftime to 20 minutes and introducing more frequent cooling breaks could better protect players from extreme heat.
Nine of the 16 host cities for the 2026 World Cup confront conditions considered 'extreme risk' for heat-related illness, posing player safety concerns and fuelling calls for more mandatory cooling aids during matches or schedule changes.
"Heat conditions are a serious topic that affect football globally," world football's governing body FIFA told Reuters.
"Discussions on how to manage with heat conditions need to take place collectively .
.
.
The protection of players must be at the centre.
"With the semi-finals and final scheduled for 3pm local time at New Jersey’s MetLife Stadium, where temperatures could reach 32 degrees Celsius, the heat debate is set to intensify.
Suggestions for 2026 contain scheduling midday games in covered stadiums to combat heat stress.
Thunderstorms have also caused disruptions, with matches suspended as players left the pitch and fans sought shelter.
Chelsea manager Enzo Maresca criticised having the United States as hosts after a two-hour weather postpone marred his team's last-16 win over Benfica in Charlotte.
Their knockout match in a half-empty stadium of under 26,000 at the start showed how attendances have also been underwhelming for matches involving European clubs, with South American and Arabic fans providing much of the tournament’s vibrancy.
Despite the excitement on the pitch, FIFA’s website still lists plenty of tickets available for remaining games, including next week's semi-finals and the July 13th final, raising questions over the tournament’s broader request in the US.
As FIFA reflects on the Club World Cup’s successes and challenges, the lessons learned will be critical in shaping the path to the 2026 World Cup, where similar issues may loom large.
