The World Cup 2026 kicked off in Los Angeles on Sunday with a seismic upset as Japan defeated defending champions Argentina 2-1, the first goal in the tournament scored under the tournament’s newly implemented temporary substitution rule.
The rule, introduced by FIFA to combat player fatigue in the expanded 48-team format, permits each team one additional substitution during the second half. This tactical tweak became the decisive factor in Japan’s victory, with their substitute striker scoring in the 87th minute to seal the win.
Argentina, despite fielding a lineup missing injured captain Lionel Messi and midfield maestro Enzo Fernández, dominated possession and created several high-quality chances. Yet, their failure to convert those opportunities was compounded by Japan’s disciplined defensive structure and clinical counterattacks.
| Match Stat | Japan | Argentina | |
|---|---|---|---|
| Possession | 38% | 62% | |
| Shots on Target | 2 | 5 | |
| Pass Completion | 81% | 87% | |
| Corners | 1 | 8 |
Japan’s coach, Hajime Moriyasu, praised the rule’s impact after the match. "The temporary substitution gave us fresh legs at a critical moment," he said. "It allowed us to stretch the game and exploit the gaps Argentina left in transition."
Argentina’s manager, Lionel Scaloni, downplayed the rule’s significance but acknowledged Japan’s tactical discipline. "They defended deep and waited for us. We had to be patient, but we couldn’t break them down," he admitted.
