5 most valuable football clubs in the world

#1: Manchester United - $4.583 billion

After being floated on the London Stock Exchange in 1991, Manchester United was purchased by Malcolm Glazer in May 2005 in a deal valuing the club at almost £800 million, after which the company was taken private again, before going public once more in August 2012, when they made an initial public offering on the New York Stock Exchange.

Currently worth $4.583 billion, the club is the only professional English club to have won every ongoing honour available to the first team that is organised by a national or international governing body.

Since the start of the 2015–16 season, Adidas has manufactured Manchester United's kit as part of a world-record 10-year deal worth a minimum of £750 million while a $80m-a-year shirt deal worth $559m over seven years features the logo of General Motors brand Chevrolet.

Their stadium, Old Trafford, has a capacity of 74,994 and opened to the public way back in 1910.
