INFOGRAPHIC: Man United beat Barcelona and Real Madrid to top football's rich list

Manchester United are back on top of the Deloitte Football 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 next year.

Now in its 20th year, the Deloitte study ranks the world's richest football teams by turnover during the 2015/16 season and this year's top three of United, Barcelona and Real is the same as the first edition in 1997.
