Qatari banker Sheikh Jassim bin Hamad Al Thani has made an improved bid to secure Manchester United from the Glazer family, a source close to the bid told AFP on Tuesday. Sheikh Jassim is in a bidding war with British billionaire Jim Ratcliffe after the pair emerged as the main contenders to buy the Premier League giants. Ratcliffe appeared to be the front runner when a third round of bidding closed last month. INEOS chemical company founder Ratcliffe, a boyhood United fan, had reportedly placed a higher valuation on the club as he seeks a majority stake.
