Has any team won back-to-back World Cups? Messi and Argentina look to repeat

Lionel Messi and Argentina will enter the 2026 FIFA World Cup as defending champions, having won the title in Qatar in 2022. The 2026 tournament, hosted across the U.S., Canada, and Mexico, will expand to 48 teams, up from 32. Only two nations have ever won back-to-back World Cups — Italy in 1934 and 1938, and Brazil in 1958 and 1962 — meaning no team has achieved the feat in nearly 70 years.
