Second bids for Manchester United have to be lodged by 9pm on Wednesday night — with the club set to be sold for a world-record fee should the Glazers accept one of the offers.
Those who want to buy the club outright, or make a partial investment, were on Tuesday night finalising their bids ahead of a significant day.
The Qatar-based Sheikh Jassim bin Hamad al-Thani bid, revealed by Sportsmail, is still the favourite, although a rival offer from Sir Jim Ratcliffe is gathering momentum.
Ratcliffe, the British billionaire owner of INEOS, who claims to be a lifelong United fan, could link up with one of a number of other interested parties in a strengthened offer, according to those familiar with the situation.
