On Monday, the Swedish top flight witnessed remarkable events as Mjällby AIF, the underdogs and darlings of the Allsvenskan season, triumphed over giants IFK Göteborg to secure an astonishing league title.
The pivotal 2-0 win ignited jubilant celebrations on the pitch, establishing an insurmountable 11-point lead for Mjällby with three matches left in the season. The club, which originates from the small fishing village of Hällevik (population: 800) along the Baltic Sea, is set to compete in the UEFA Champions League in the 2026-27 season.
The remarkable journey of Mjällby is further highlighted by their coach, Anders Torstensson, a former school principal who only began coaching professional football in 2023. The team was on the brink of disappearing while struggling in the Swedish third tier in 2016 due to financial difficulties. Operating on a limited budget, they have focused on developing young talent and transitioning them to larger clubs across Europe.

Mjällby returned to the Allsvenskan in 2020 and established themselves as a midtable team, finishing fifth last season, 15 points behind champions Malmö. Their impressive form in the 2025 season propelled them to achieve the first top-flight title in the club’s 86-year history.
Unsurprisingly, Mjällby’s underdog success has drawn parallels to Leicester City’s shocking Premier League victory in 2015-16.
In light of this, here are a few other remarkable title victories that have occurred in European top-flight football.
After finishing 14th in their first Premier League season back in 2013-14, Leicester surged from 5,000-1 outsiders to champions of England. Under Claudio Ranieri, with stars like Jamie Vardy, Riyad Mahrez, and N’Golo Kanté, they outpaced all competitors to clinch the Premier League title by a 10-point margin—matching the gap to avert relegation the following season.
In Italy, amid the brilliance of Diego Maradona and Michel Platini, it was the underdog Hellas Verona that ascended to claim the Scudetto. The Gialloblu lost only two matches that season while other heavyweights like Juventus, Napoli, AC Milan, and Internazionale faltered. This victory remains Verona’s only Serie A triumph to date.
Before Paris Saint-Germain began their current dominance in Ligue 1, Montpellier secured the 2011-12 title, disrupting PSG’s ambitious plans, with star striker Olivier Giroud leading the scoring. Montpellier finished three points ahead of Zlatan Ibrahimovic and Co., marking their first and only major top-flight trophy, before being relegated to Ligue 2 last season.
After a rebranding in 2014, Istanbul Basaksehir experienced a brief but brilliant period in the Turkish Süper Lig, finishing runners-up in 2016-17 and 2018-19 before claiming the title in 2019-20—becoming only the second club other than Turkey’s “Big Four” (Galatasaray, Fenerbahce, Besiktas, and Trabzonspor) to win the league since its inception in 1959.
Though Kaiserslautern won the German Cup the same season they were relegated from the Bundesliga in 1995-96, they made a sensational comeback by winning the league after being promoted. Under the management of Otto Rehhagel, they stunned defending champions Bayern Munich in their first game back, narrowly defeating them to the title with one match remaining—making them the only newly promoted team to win the Bundesliga. Rehhagel would later lead Greece to victory at Euro 2004, adding to his legacy.
One of the greatest upsets in modern Bundesliga history occurred in 2023-24 when Bayer Leverkusen ended Bayern Munich’s 11-year title streak. Under Xabi Alonso, Leverkusen transformed from second-to-last in the league with just five points from eight matches when he took over in October 2022, to achieving a league and cup double without losing a domestic game throughout the next season.
