Prospective Manchester United owner Sheikh Jassim bin Hamad Al Thani has been described as being 'difficult to read' in board meetings.
The Qatari banker is the frontrunner to take over from the Glazers at Old Trafford, with INEOS chairman Sir Jim Ratcliffe also battling for control. Little is known about Jassim, who appeared out of obscurity to launch his bid in February.
Jassim did not attend the presentation United hosted at Old Trafford, instead sending representatives of his Nine Two Foundation. The Qatari has instead kept a low profile aside from submitting improved offers to buy out the Glazers.
