Bayer Leverkusen hold the record of the longest unbeaten run in European football history after surpassing Benfica’s long-standing tally of 48 games without defeat.

Xabi Alonso’s side enjoyed a remarkable 2023-24 campaign, with the Spaniard guiding the club to their first-ever Bundesliga title.

They also reached the final of both the DFB-Pokal (which they won) and the Europa League, but faltered against Atalanta in the latter to lose their stunning unbeaten streak of 51 games without defeat.

The 10 longest unbeaten runs since the introduction of European club competitions

Although Leverkusen have the longest unbeaten streak in European history, there are several other top teams who have enjoyed extended periods without being defeated.

Eusebio-led Benfica had previously held the record for 59 years, following their 48-game unbeaten run from December 1963 to February 1965.

Dinamo Zagreb have the third-longest unbeaten run in European football of all-time, with the Croatian side going 45 games without defeat from November 2014 to September 2015. Fellow Croatian outfit Rijeka also have a 45-game unbeaten streak and are therefore joint-third.

Rangers are in fifth place with a 44-game unbeaten run in the early 1990s. The Scottish giants won a domestic treble and even went unbeaten in the Champions League, but failed to qualify for the knockout stages after too many draws.

In sixth is Juventus. The Old Lady went 43 games unbeaten under Antonio Conte during the 2011-12 season, with their only defeat coming against Napoli in the Coppa Italia final.

AC Milan, Ajax and Celtic are joint-seventh. They each have a 42-game unbeaten streak under their belts, while Welsh side The New Saints complete the top 10.

Incredibly, Ajax would have enjoyed a 74-game unbeaten run had they not lost to Feyenoord in the DNVB Beker quarter-final in March 1995. They hadn’t tasted defeat in 32 matches before that loss and enjoyed their 42-game unbeaten streak following the defeat.

The all-time unbeaten run record in football history

While Leverkusen hold the record of the longest unbeaten streak in European football history, they only sit in fourth place on the list of all-time unbeaten runs.

Celtic, Union Saint-Gilloise and Al-Ahly have all enjoyed longer unbeaten runs, although the former two completed their spells of dominance before the introduction of UEFA club competitions and the latter does not compete in Europe due to being an Egyptian team.

However, Celtic currently hold the all-time record of 66 games unbeaten - achieving this feat from 1915 to 1917. Union SG are second with an unbeaten streak of 60 games (1933-1935), while Al-Ahly are third on 55 games unbeaten (2004-2005).

The longest unbeaten run in international football

In regards to international football, Italy hold the longest unbeaten run. They didn't taste defeat for 37 games from September 2018 to September 2021.
