The announcement that the Glazer family has put Manchester United up for sale after 17 years of ownership has already led to a number of their fellow billionaires expressing interest.
Manchester United are one of the most popular sports teams in the world, with the Glazers claiming in their announcement on Tuesday that United have 1.1billion supporters.
Given that Chelsea Football Club sold for £4.25billion earlier in the year, the belief around Old Trafford is that a figure north of £5bn will be needed for any interested billionaire to win the race to buy Manchester United.
