The Qatari billionaire has made five bids for the Red Devils, hoping to outbid British millionaire Sir Jim Radcliffe.
Jassim wanted 100% of the club, whilst Radcliffe was only looking for a workable majority that would allow the Glazers to remain stockholders.
The Qatari has promised to pay off United’s massive debts and invest in Old Trafford and the training ground.
Given that the club was put up for sale ten months ago, the Glazers have been accused of dragging their feet in discussions.
Supporters are worried that the Americans want to stay at Old Trafford.
According to the Sun, Jassim has won the election and United expects him to take over in November.
That will be one year after the Glazers put the club up for sale, and the Americans will have spent nearly 19 years at the club.
The Americans have extracted more than £1.2 billion out of the club while investing only £180 million of their own money in a £780 million takeover in 2005.
While United fans hoped that a takeover would be completed before the summer transfer window, the club’s transfer budget would not have increased significantly due to Financial Fair Play restrictions.
