MANCHESTER UNITED are once again being linked with a takeover as rumours swirl over a mystery bid.Saudi boxing chief Turki Alalshikh claimed negotiations over a sale are at an “advanced stage”.AlamyThe Glazer family and Sir Jim Ratcliffe’s resolve may be tested by a takeover bid at Manchester United[/caption]GettyTurki Alalshikh suggested a deal was close to being done but refused to reveal who the mystery bidder is[/caption]Alalshikh suggested a new investor is hoping to buy out the Glazer family and Sir Jim Ratcliffe. He wrote: “The best news I heard today is that Manchester United is now in an advanced stage of completing a deal to sell to a new investor.“I hope he’s better than the previous owners.”United have played down the claims and insisted they were unsure what they were based on.But Alalshikh doubled down with a follow-up post on X.He added: “My yesterday’s post about Manchester United’s potential sale meant one thing: the club is in an advanced negotiation phase with a new investor.“Just to clarify, I am not the investor, nor are they from my nation. I’m posting this as a fan who wishes the deal to happen, though it might not necessarily happen.”Majority owners the Glazer family rejected a huge offer from Sheikh Jassim At Thani’s Qatar-based consortium almost two years ago.CASINO SPECIAL – BEST CASINO BONUSES FROM £10 DEPOSITSInstead they accepted Ratcliffe’s £1.25billion offer for a 27.7 per cent stake in the club – which was finalised early last year. But with United now valued at around £5.2bn, who are the possible candidates hoping to land a mega deal to buy the Old Trafford club? SAUDI ARABIAOne possible option is a bid from the Saudis and Alalshikh himself. This would be separate from the Public Investment Fund which bought Newcastle in 2021.Alalshikh is chairman of the Islamic Solidarity Sports Federation, who have hosted various big boxing fights in Saudi Arabia.And after reports of interest in buying Bristol City, could Alalshikh make the step up to try and buy his beloved United?QATARAlalshikh, though, insisted he was not the alleged mystery bidder – and that they do not come from his country.That could, therefore, mean the bidder is from neighbouring Qatari investors. Although SunSport understands it would not be from the Qatari Sports Investment government-funded organisation which owns Paris Saint-Germain. BROOKLYN EARICK / DAN GILBERTBrooklyn Earick enquired into a shock takeover of Tottenham as part of a US consortium.The DJ was understood to be backed by Dan Gilbert, the owner of the Cleveland Cavaliers NBA franchise who has an estimated fortune of £20bn.And the pair could combine again to launch another bid for a Premier League powerhouse.But after failing to stump up enough cash to buy Spurs, it is unlikely the consortium would have enough to convince the Glazers to sell.
