Real Madrid and Barcelona have been overtaken by Manchester United in the Deloitte Money League which determines the world's richest clubs.
United have topped the money league for the first time since 2005 but the pound's fall against the euro means they may struggle to beat Barcelona and Real Madrid again next year.
Real, who had topped the list for 11 years, were beaten to second place by their La Liga rivals Barcelona by just €100,000, ESPN FC reports.
United, on the other hand, have surged ahead of the pack, becoming the first football team to earn more than £500 million in a season.
United earned a total revenue of £515m is almost £50m more than Barcelona and Real generated for the 2015/2016 season.
