Sheikh Jassim bin Hamad Al Thani wants immediate full control of Manchester United.
The Glazers have been exploring a sale, but are yet to receive their 5bn asking price.
It has been speculated that the Glazers could instead seek significant investment in exchange for a minority stake in the club, which would see them remain in power.
Sheikh Jassim, however, will not enter such an arrangement.
According to CBS Sports reporter Ben Jacobs, Sheikh Jassim's bid is "all or nothing".
He will NOT buy a minority share, even if it was to be with a view to eventually becoming majority owner.
