Manchester City owner Sheikh Mansour bin Zayed Al Nahyan has toppled Roman Abramovich to head British football's rich list.
Sheikh Mansour, a member of the royal family of Abu Dhabi, has a personal fortune of £15billion according to the Football Rich List, researched and published by FourFourTwo magazine.
The 38-year-old bought City in the summer, while Abramovich, Chelsea's Russian owner, has slipped to third in the list - his wealth is estimated at £7billion and he has been said to have lost over £3billion in the economic downturn.
He has also been overtaken in the list by Lakshmi Mittal, the 58-year-old Indian industrialist worth £12.5billion who joined Formula One's Bernie Ecclestone and Flavio Briatore investing in Queen's Park Rangers.
David Beckham remains the richest player associated with British football - his personal fortune of £125million being streets ahead of his closest rivals Michael Owen (£40million) and Wayne Rooney (£35million).
Beckham is 38th in the overall list, while England head coach Fabio Capello is at number 73 worth an estimated £25million with a £6million-a-year contract and a £10million private art collection.
Sir Alex Ferguson is at number 78 in the list (£22million) and Arsenal manager Arsene Wenger at number 92 (£14million).
Celtic shareholder Dermot Desmond, the Irish entrepreneur, is the richest person in Scottish football - he is eighth on the list and said to be worth £1.2billion. Rangers chairman Sir David Murray is 19th on the list, worth £600million.
Despite the huge fortunes of the wealthiest owners, football finance experts fear British football's bubble may be about to burst.
Professor Tom Cannon told the magazine: "Season-ticket numbers will probably be down by about 10% but renewals will be down by at least 15 or 20%. That's where the problems will be as you go down the divisions."
