AI ranks every London football club from biggest to smallest | OneFootball

There are currently 14 professional clubs in the capital this season

English football has its fair share of clubs who are now seen as global brands as well as on-pitch sides, as well as those further down the pyramid who are at the heartbeat of a local community.

Perhaps nowhere else in the country emphasises the aforementioned statement as much as the capital itself, London.

There are currently 14 clubs across the Premier League, Championship, League One and League Two who are based in an area of the city, and as a result, there are several hotly-contested encounters which take place between these sides.

Some of those are currently harbouring ambitions of promotion, which could see them face off in even more London derbies next season, whilst others are hoping to steer clear of the relegation zone in their respective division.

Whilst that is very much the case, it has often been argued, particularly amongst those who support one of English football's stereotypical 'big six' sides, as to which club currently rules the roost in the capital.

With that being said, Football League World has put AI to the test to see if the old-age question can be answered, and ChatGPT has ranked all 14 sides who are currently based in London and within the '92' professional-club bracket for the 2025/26 campaign in size.

1 ? ? Arsenal

According to AI, the biggest professional club in London are Arsenal, with the Gunners looking to end a 20-year wait for a Premier League title this season after a handful of near misses under Mikel Arteta.

Arsenal's trophy cabinet, to an extent, backs up the logic presented by the computer, with the North London side winning 48 trophies in total ahead of the current season, and that can certainly be added to in the coming weeks.

This, alongside the global reach they are able to attract beyond the 60,074 supporters that pack out the Emirates Stadium every single matchday are seen as the biggest factors behind what some would argue is a controversial selection.

2 ? ? Chelsea

In second place are Chelsea, who have become a dominant force in the modern era, largely due to the millions plugged in by previous owner, Roman Abramovich.

Five of the Blues' six top-flight trophy wins have come in the past 21 years, whilst they are the only English side to have 'won it all' after emerging as Club World Cup winners in the summer of 2025 after previously becoming the first London side to win the UEFA Champions League twice.

Despite Stamford Bridge not being the biggest stadium in the country, the Kings Road club's global following has also been taken into account by AI.

3 ? ? Tottenham Hotspur

In third place are Tottenham Hotspur, who currently have their top-flight status under threat for the first time since 1978.

Despite the North London club's domestic struggles, Spurs were able to end a 17-year wait for a major trophy at the end of last season by defeating Manchester United in the UEFA Europa League final.

Tottenham have also entered a new era within the past decade, showcased by the 62,850-seater Tottenham Hotspur Stadium which replaced White Hart Lane in April 2019.

Although it remains to be seen when they will next feature in Europe, their regular involvement in the Champions League within the past 15 to 20 years has also been acknowledged as a major factor.

4 ? ? West Ham United

Rounding off the top four are West Ham United.

According to AI, the Irons have one of the largest national followings, with it being stereotyped that the club attract a large number of supporters from the Essex region, and that their global reach is starting to grow as a result of recent developments.

This includes the somewhat controversial move to the London Stadium in 2016, as well as their stints in Europe at the start of the 2020s, during which the Hammers lifted the UEFA Conference League trophy in Prague three years ago after dramatically defeating Fiorentina.

5 ? ? Crystal Palace

Just below them are Crystal Palace, who won their first-ever major honour by shocking Manchester City in the 2025 FA Cup final.

As referenced by AI, the Eagles have established themselves as a stable Premier League side since gaining promotion through the play-offs in 2013, and are now looking to push forward despite the pending exit of Oliver Glasner from Selhurst Park.

Their recent progress was also shown in the 2026 winter transfer window, when they smashed their record spend for an incoming twice, on Brennan Johnson and Jorgen Strand Larsen from Tottenham and Wolverhampton Wanderers respectively.

6 ? ? Fulham

In sixth are Fulham, who have largely earned their position by becoming an established Premier League side in two stints since the turn of the millennium.

Beforehand, the Cottagers had spent years without being in the top-flight, but had always been a historic London-based club, which is still echoed by some parts of Craven Cottage.

Despite not being in the same category as Chelsea and Spurs, the Whites are currently in a strong financial position to push forward.

7 ? ? Brentford

At the halfway point are the final Premier League side in the form of Brentford.

After spending decades in the lower reaches of the EFL, the Bees' successful 'moneyball' business model eventually saw them rise into the Premier League five years ago, and they have certainly solidified their position.

AI has acknowledged that they have a small, but loyal core of supporters, and that their smart recruitment policy is only likely to see the West London club continue growing over time.

8 ? ? Millwall

In eighth place is the first Championship side on this list, Millwall.

AI believes that the Lions have a large identity and presence within the English game for several reasons, despite the fact they have only spent two seasons in their history inside the top-flight.

However, that could soon change, with Alex Neil's side currently in the thick of an enthralling promotion battle.

9 ? ? Queens Park Rangers

They are followed by Queens Park Rangers, who have been outside the Premier League for over a decade.

Despite being a historic club within the ether of West London, the Hoops' recent shortcomings - which have been impacted by previous overspending - have been acknowledged by AI.

On top of this are the current facilities on offer at Loftus Road, which has a capacity of 18,439.

10 ? ? Charlton Athletic

The final Championship side on this list are Charlton Athletic.

In recent history, the Addicks have bounced between the second tier and League One more often than not, but their spell of seven successive years in the Premier League between 1998 and 2007 have not been forgotten about.

As a result, it may be a shock to some that they are the lowest-ranked Championship side on this AI-based list.
