Manchester United bidder Sheikh Jassim Bin Hamad Al Thani is 'concerned' that the Glazers may not sell the club, reports have said.
Both he and Sir Jim Ratcliffe submitted bids in excess of £5billion in May, but the Manchester Evening News claims Sheik Jassim is yet to receive a response from the club.
Mail Sport reported earlier this month that negotiations were still ongoing, with the Qatari bid thought to be slightly ahead, although the current owners' £6bn valuation is not believed to have been met.
It comes nine months after the Glazers, who have owned United since 2005, initially announced they were willing to sell the club.
