Takeover talk has been sweeping across Old Trafford with reports Saudi Arabia's second in command, Crown Prince Mohammad, is considering an offer to buy the club.
The Saudi crown prince is worth around £850billion, while a serious bid for United is expected to come in at over £3bn - the value of the Glazer family's current shares.
United co-chairman Avram Glazer is even due to attend the Future Investment Initiative conference in Saudi Arabia's capital Riyadh next week, alongside leading bankers and investors based around the globe.
If a takeover was completed, it would cement United's status as global football's most powerful club financially.
