Manchester United owners the Glazers have told prospective buyers they have 10 days to submit improved offers for the club.
The Glazers put United up for sale in November and have received offers from INEOS chief Sir Jim Ratcliffe and Qatari banker Sheikh Jassim bin Hamad Al Thani. Neither of those bids are thought to have come close to the Glazers' valuation of the club.
Representatives of Sheikh Jassim, who wants to buy 100 per cent of the club, will attend Old Trafford on Thursday to watch a presentation on the takeover process. Ratcliffe, who wants to buy just the Glazers shares (69 per cent), will do the same the next day.
