South American sides have never lost a World Cup hosted in North America. Brazil lifted the trophy in Mexico 1970 and USA 1994, while Argentina won in Mexico 1986. That flawless 100% record frames this summer’s tournament, where travel distances rival those between London and Mumbai, yet many players feel a cultural home‑advantage and passionate fan bases rallying behind them.

Recent Copa América experience gives Brazil and Argentina a modest edge. The 2024 edition in the United States exposed teams to heat, travel and mixed crowds, mirroring World Cup conditions. Brazil’s coach Ancelotti still tweaks a four‑forward system after a 6‑2 friendly win, while Argentina fields essentially the Qatar champions, now 38‑year‑old Messi leading a largely unchanged backline. Ancelotti admits midfield depth remains thin.

Colombia and Uruguay arrive bruised; Colombia’s 28‑game unbeaten run ended at the Copa América final, while Uruguay’s attack stalled after Luis Suárez’s retirement and a 5‑1 loss to the U.S. Paraguay and Ecuador, meanwhile, ride defensive solidity into the tournament. With Brazil and Argentina shouldering the continent’s hopes, the North American stage will test whether the 100% record survives. Knockout rounds could produce major upsets.
