Madrid top rich list again
Real Madrid have retained their place as the most valuable football team in the world for a third straight year, but Manchester United could soon topple them.
The reigning European champions' value has dropped five per cent to $3.26billion (£2.13billion) this year, but their £746million (£489million) revenue is the highest of any sports team in the world.
Rivals Barcelona are second in the 2015 list with a value of $3.16billion (£2.07billion), followed by Manchester United at $3.10billion (£2.03billion).
Unlike the Spanish giants, however, the value of Louis van Gaal's side has grown this year, with Forbes reporting a 10 per cent increase.
No club are as adept at acquiring sponsorship as United, with US car giant Chevrolet's kit sponsorship deal worth a reported £53million per season.
Next term the coffers are to be boosted further after a mammoth £750million deal was struck with Adidas - a "global technical sponsorship and dual branded licensing deal" running for 10 years.
United believe it is the biggest kit deal in sport and may well help them surpass Barcelona and Real Madrid, especially given the recent £5.136billion domestic television deal.
Tottenham, Newcastle and West Ham complete the Premier League's representation.
