The Glazers have a key concern over Sheikh Jassim's plans to buy Manchester United.
Both Sheikh Jassim and rival Sir Jim Ratcliffe have made new offers reaching 5bn over the past week.
However club owners, the Glazers, have one major concern regarding Sheikh Jassim's offer - which would include wiping the club's debt.
But the Independent says the Owners and Directors Test is expected to take far longer for the Qatari after the Premier League tightened up its regulations on state-linked owners.
Meanwhile, Ratcliffe's INEOS group are insisting they will have a much smoother - and quicker - process in taking charge.
