The 20 richest football clubs in the world

Deloitte has once again released its Football Money League, charting the gargantuan revenues of Europe's top-flight clubs.

This year, Manchester United became the first club to surpass a £500 million turnover, which was enough to deny Real Madrid of their top spot on the list for the 12th year running.

Not much has changed in the long run, though, the League's top three clubs have remained the same since Deloitte launched the study 20 years ago, in 1997.

Combined Money League club revenues increased by a massive 12% this year, reaching a total of £5.5 billion across the top 20 teams.

Deloitte estimates that due to record television contacts, all Premier League clubs will be in the top 30 by next year.
