#3 Andrea Agnelli (Juventus) - $19.1 billion
One of the most important individuals in the planning of the controversial European Super League, Andrea Agnelli has helped Juventus become a feared side in Europe.
Agnelli's decision to appoint Antonio Conte as manager of Juventus in 2011 began the club's dominance domestically. The Bianconeri have won nine consecutive Serie A titles, making some shrewd acquisitions and creating a world-class squad full of talented individuals.
However, Agnelli's insistence on proceeding with the European Super League has been met with intense criticism. It remains to be seen what the next steps will be, as the football world has been shaken to its core in the last 24 hours.
#2 Dietrich Mateschitz (RB Leipzig / Red Bull Salzburg) - $26.9 billion
The Red Bull group of football clubs have become renowned for their talent-spotting ability, and backing them is Austrian billionaire Dietrich Mateschitz.
Red Bull Salzburg have sold the likes of Erling Braut Haaland, Takumi Minamino and Dominik Szoboszlai in recent transfer windows, while RB Leipzig are one of the best teams in the Bundesliga. Players often traverse the Red Bull Salzburg to RB Leipzig path, and Szoboszlai, Peter Gulacsi, Konrad Laimer and Dayot Upamecano have all done so.
RB Leipzig, like Hoffenheim, have come under criticism from Bundesliga fans for their quick rise, with financial backing from Mateschitz seen as a key reason.
#1 Sheikh Mansour (Manchester City) - $30 billion
Like Abramovich and Chelsea, Sheikh Mansour's investment in Manchester City has transformed the club.
Sheikh Mansour acquired Manchester City in 2008 and started spending money almost immediately. There were a few stutters initially, but the Cityzens are now one of the best sides in Europe, managed by arguably the best manager in the world.
The likes of Sergio Aguero, David Silva, Vincent Kompany and Yaya Toure were key players in establishing Manchester City as a Premier League force. The current side under Pep Guardiola were among the favourites to win the Champions League this season before the announcement of the European Super League.
