Sheikh Jassim bin Hamad Al Thani is prepared to pay over the odds to complete a full takeover of Manchester United.
Representatives of Sheikh Jassim were at Old Trafford on Thursday for talks with United officials and to receive a presentation on the club.
The Qataris have offered an opening €4.5bn, which has been rejected by the Glazer family.
However, Sky Sports says Sheikh Jassim intends to raise their offer to €6bn - which would satisfy the Americans.
The proposal will also be too rich for Sir Jim Ratcliffe to compete with. Ratcliffe was at Old Trafford on Friday for talks.
