The UEFA Champions League 2025/26 season is underway, and Matchday 1 delivered a thrilling start to Europe’s biggest club competition. Continuing its revamped 36-team format, fans were already treated to a delightful number of fixtures, heavyweight clashes, and performances that set the tone for what promises to be yet another historic season.

A Revamped Format

This year makes it the second season of UEFA’s new “Swiss-style” league phase. Instead of the traditional eight groups, 36 teams are placed in one league table. Each team plays eight matches against different opponents, four at home and four away. The top eight qualify directly for the round of 16, while teams ranked ninth to 24th enter a playoff.

This design was introduced for the 2024/25 season gaining a lot of commercial success for UEFA, while the fatigue within the fixtures made it a cause of concern, it also promised fresh design that aims to create more variety, more big matches, and more drama across the calendar. Matchday 1 proved that the change is already delivering.
