5. AC Milan (1991-92)
With 18 league titles and seven Champions League trophies, AC Milan stands as one of football’s most illustrious and dominant clubs. A true European powerhouse, the Rossoneri etched their name into football history during the 1991/92 season with an unbeaten league campaign.
Under the stewardship of Fabio Capello, Milan achieved this remarkable feat, winning three consecutive Serie A titles between 1991 and 1994. Capello’s success built on the foundation laid by Arrigo Sacchi, whose tactical genius and shrewd signings created a star-studded team featuring legends like Ruud Gullit, Marco van Basten, Paolo Maldini, and Frank Rijkaard.
During their historic unbeaten season, Milan won 22 of 34 matches, scored 74 goals, and conceded only 21. This dominance extended beyond a single campaign, as the Rossoneri set a Serie A record with a 58-match unbeaten streak that remains unbroken to this day.
4. Celtic (2016-17)
Although Celtic do not belong to the top five European leagues, they are rightly regarded as a European giant. The club boasts a storied history, including their legendary European Cup triumph in the 1966-67 season.
Their most notable recent success came in the 2016-17 season under former Liverpool manager Brendan Rodgers. During his tenure, the Celts achieved an extraordinary 69-game unbeaten streak and secured a record-breaking 106 points.
That remarkable campaign saw Celtic dominate Scottish football, winning the Scottish Premiership, Scottish Cup, and Scottish League Cup to achieve an unprecedented domestic treble.
3. Rangers (2020-21)
The 2020/21 season was truly unforgettable for Rangers fans, as their team delivered a remarkable campaign marked by record-breaking achievements.
Rangers competed in 56 matches across all competitions, culminating in a 4–0 victory over Aberdeen on the final day of the league, securing an undefeated league season. They also became the first club since Celtic in 2016–17 to surpass the 100-point milestone. Dominating at Ibrox, Rangers won all 19 home league games and matched the league record with an incredible 26 clean sheets.
Setting a new British record, the team conceded only 13 goals across 32 wins and six draws in the league. Under the inspirational guidance of Steven Gerrard, Rangers cemented their place in football history, delivering one of the most outstanding seasons ever witnessed in the sport.
2. Ajax (1994-95)
Based in the Netherlands’ capital, Ajax Amsterdam has long been a powerhouse in both Dutch and European football. Boasting four European Cups, the club is among the most decorated in Europe. Their most iconic triumph came in 1995 when they edged past AC Milan 1-0 in the UEFA Champions League final, capping off a remarkable season.
Ajax achieved the incredible feat of winning the tournament without losing a single match, becoming the only Dutch team to do so. Under Louis van Gaal’s guidance, they also clinched two domestic titles that year, completing a historic treble and cementing their legacy as one of football’s greatest sides.
1. Bayer Leverkusen (2023-24)
One of modern football’s most captivating fairytales unfolded in the Bundesliga with Bayer Leverkusen’s remarkable unbeaten run. Xabi Alonso took charge of the club in 2022, inheriting a side languishing in eighth place. Fast forward 18 months, and Leverkusen not only clinched the league title with five games to spare but also went undefeated the entire season.
Defying the odds and rewriting their narrative, Leverkusen shook off their reputation as “Bayern Neverkusen” – a moniker born from their history of agonizingly close misses. Instead, they crafted a triumphant story of resilience, belief, and breathtaking football.
