Arsenal co-owner Alisher Usmanov has climbed to the top of the Sunday Times Rich List for 2013, which is to be published tomorrow.
The 59-year-old Uzbek investor is believed to be worth around £13.3b - £4b more than Chelsea owner Roman Abramovich, who is ranked fifth on the list.
Usmanov owns a 30% share in the Gunners along with American Stan Kroenke, but is rumoured to be planning a takeover bid in the near future.
He originally bought a 14.5% stake in the club back in August 2007.
