Malcolm Glazer has made a new £800m bid to take over Manchester United, the English Premiership club has confirmed.

Glazer, the owner of the NFL team Tampa Bay Buccaneers, has built up a a 28.1 percent stake in United but has been rebuffed on three occasions in his attempt to take over United.

Glazer’s chances of success depend on the 28.9 percent share in the club owned by Cubic Expression, the company owned by Irish racehorse tycoons John Magnier and JP McManus. They have given no indication as to whether they are prepared to sell to Glazer.

In the meantime the club issued a statement to the Stock Exchange to confirm the bid.

“The board of Manchester United stated on December 20 that the Glazer Family Partnership had indicated potential revisions to its previous proposal and that Manchester United did not intend to open discussions on this matter until it had received a definitive proposal,” United said in a statement .

“The board has noted the recent press speculation on this subject. The board can confirm that it has now received a detailed proposal subject to various pre-conditions which may form the basis of an offer for Manchester United from Glazer.

“A further announcement will be made in due course.”
