In one of the most remarkable underdog stories in recent Swiss football history, promoted side Thun have captured the Swiss championship in stunning fashion—clinching the title with three matches still to play in the season.

Mauro Lustrinelli's squad secured their first major trophy without even needing to take the pitch on the decisive day. Their closest rivals, St. Gallen, suffered a crushing 3-0 defeat at the hands of Sion, handing the championship to the jubilant Thun faithful.

The title win was particularly sweet after a brief setback. Thun had a golden opportunity to seal the championship early but stumbled in a 3-1 loss to dethroned holders Basel on Saturday. However, the delay only added to the drama. Back at their own stadium, players and fans gathered to watch St. Gallen's match on the big screens, erupting in celebration as the final whistle confirmed their historic triumph.

This is a story of resilience and perseverance. The club, hailing from the small town of just 45,000 residents in the canton of Bern, spent five long years toiling in the second division before earning promotion in 2025. Now, as Swiss champions, they will enter the Champions League second qualifying round—a fitting reward for their incredible journey.

Interestingly, this isn't Thun's first taste of European competition. Back in the 2005-06 season, they qualified for the Champions League as Swiss runners-up and even made it all the way to the group stage. For a club of their size, that remains a legendary achievement—and now they have a chance to write a new chapter on the continental stage.
