There are 13 soccer clubs on the planet worth more than $1 billion each, according to KPMG.

The financial service firm published its report on "The European Elite 2019: Football Clubs' Valuation" on Monday, and it shows six English clubs are in its top 10 list, while four have pushed past the $3 billion threshold.

The report highlights how the "big five" domestic soccer leagues in Europe - England's Premier League, Spain's La Liga, Germany's Bundesliga, Italy's Serie A, and France's Ligue 1 - have retained their power in the sport.

The only thing that really changes year on year is the placement of the wealthiest - and therefore the best - clubs.

KPMG identifies a club's worth by its "enterprise value," calculated using an algorithm that looks at five factors:

1. Profitability, which considers the ratio of staff and player costs to revenue;
2. Popularity, looking at the number of followers each club has on social media platforms like Facebook, Instagram, Twitter, and YouTube;
3. Sporting potential, or a club's overall roster value, which is calculated using a "Player Valuation" tool;
4. Broadcasting rights, which KPMG says "play a fundamental role in the revenue generation potential" of soccer clubs;
5. Stadium ownership, which, after squad value, can be one of the greatest assets a soccer club has.
