The best teams in the world contain many familiar names. Although some of the so-called big teams are not doing such a good job of winning trophies.

Others do nothing but lift silverware. All the clubs tend to have one thing in common: fairly big and new stadiums and a growing, global fanbase.

With Artificial Intelligence playing an ever-increasing part in our daily lives, it is very interesting to see who it ranks as the biggest clubs in the world. So, with that in mind, here is how ChatGPT ranks the 20 biggest clubs in the world of football.

20 Newcastle

What ChatGPT says: "A historic English club with a large following and growing financial and sporting influence."

Newcastle have the richest owners in world football, and while they only have a League Cup to show for that richness as of late, there's an expectation they can kick on in coming years after becoming a regular in European football once again after years away from the elite table.

19 Boca Juniors

Argentina

MixCollage-28-Dec-2023-03-16-PM-961

What ChatGPT says: “An iconic global identity, passionate fanbase and strong continental pedigree."

Boca Juniors are one of the most famous clubs in the world and arguably have a global reach that matches or exceeds some of the top sides in Europe. Their famous blue and yellow strips are synonymous throughout the world of football, especially for the performances of Diego Maradona - easily one of the greatest players of all time - though it has been a while since someone with that presence made an impact on the team.

With 61 major honours, they are right up there among the most successful clubs to ever exist.

18 River Plate

Argentina

What ChatGPT says: “One of South America’s biggest clubs, with huge support and a remarkable domestic history."

While Flamengo used to make this list as South America's biggest club (after all, they are the most followed and supported club on the continent), ChatGPT has changed its mind and replaced them with Boca Juniors' arch rivals River Plate.

Their home ground, the Estadio Mas Monumental , is the largest stadium in South America, holding over 85,000 fans with an ongoing expansion project targeting a 101,000-seat capacity, having sold out their previous home for 100 consecutive matches.

17 Tottenham Hotspur

England

What ChatGPT says: “Historically, one of the top clubs in England, though less successful in recent decades. Growing wealth due to a modern stadium and increasing commercial deals.”

North London outfit Tottenham Hotspur have not won the English league title since 1961. That season they won the league and FA Cup double. Their new stadium is the finest in England, yet as of 2024, they have not won a trophy since winning the League Cup at Wembley in 2008 in a 2-1 win over Chelsea. Over the years, the club have had a variety of top-class players, including Paul Gascoigne, Dimitar Berbatov and Harry Kane.

16 Benfica

Portugal

Benfica supporters raise their scarves aloft.

What ChatGPT says: “A giant fanbase, deep history and two European Cups."

Based in Lisbon, the Portuguese giants have won two European Cups and are among the most successful clubs in their country, with decades of domestic dominance behind them.

Their influence stretches far beyond Portugal, with millions of supporters worldwide and a rich history of producing elite talent, including Eusebio, Rui Costa and Joao Felix. The Eagles’ iconic red shirts, passionate supporters and European pedigree make them a heavyweight of world football, despite operating outside Europe’s wealthiest leagues.

15 Ajax

Netherlands

Ajax

What ChatGPT says: “Dutch giants Ajax have 35 league titles to their name up to 2024 and have won the European Cup and Champions League four times.”

With Johan Cruyff pulling the strings in midfield, Ajax won the European Cup three years in a row in the 1970s. Then, with an incredibly young team, they won it again in 1995, beating AC Milan 1-0 in the final.

As the years have gone by, Ajax have had to sell their best players. So, although they have great heritage in European football, the Dutch side no longer have any real clout to sign players unless they are young and unproven.

14 Atletico Madrid

Spain

Atletico Madrid Vicente Calderon

What ChatGPT says: “One of the top clubs in Spain, with a history of success in both domestic and European football and 11 La Liga titles.”

Although Atletico Madrid will probably always be seen as poor compared to their city rivals Real, they continue to have success. Three of their 11 La Liga titles have come in the last 30 years. Current manager and former player Diego Simeone has helped the club lift two of those as boss.

They have reached the Champions League final three times. In 2014 and 2016 they lost in the final to Real Madrid. The club have still had European success, winning the UEFA Cup and Europa League three times between 2010 and 2018.

13 Borussia Dortmund

Germany

Dortmund in 1997

What ChatGPT says: “Dortmund are a popular club with a massive fanbase, who have won the Champions League along with five Bundesliga titles.”

Borussia Dortmund’s Signal Iduna Park is the biggest stadium in Germany. It has the biggest average attendance in world football, with 81,000 fans coming to watch games. Over the years, they have had some of the biggest names wear the yellow and black shirt of the club. They include Erling Haaland and Jude Bellingham. However, the club’s finest hour came in 1997 when they beat Juventus to win the Champions League final for the first time in their history.

12 Inter Milan

What ChatGPT says: “Inter Milan are a major club in both Italian and European football. As of 2024, they have 20 Serie A titles. They have also been crowned European Champions three times.”

Inter Milan won back-to-back European Cups in the 1960s. They are a club with one of the highest average attendances in world football.

Their 70,000 average attendance over the course of the 2024/25 season makes them the fourth best-supported club in the world. That is two places ahead of their city rivals AC Milan (more on them later). Inter last won the Champions League in 2010 when the enigmatic Jose Mourinho steered the club to the title.

11 Paris Saint Germain

France

Lionel Messi and Kylian Mbappe

What ChatGPT says: “Backed by Qatar's wealth, it makes PSG one of the wealthiest clubs in the world. They have been the dominant force in French football in recent years, with 12 Ligue 1 titles, and two UEFA Champions League wins.”

Ten of PSG’s 14 titles came between the years of 2013 and 2024. The Parisiens have had some of the very biggest names in football at the club. In recent seasons, they boasted Lionel Messi, Mbappe and Neymar in the same side. The Champions League remained elusive until the last two seasons, where they've swept up back-to-back titles on the continent.
