Manchester United has announced the appointment of Malcolm Glazer's sons Joel, Avram and Bryan as new non-executive directors of the club.
The announcement came as chairman Sir Roy Gardner said that he stood down from his post on 6 June.
Non-executive directors Ian Much and Jim O'Neill have also both resigned.
Mr Glazer has won almost complete control of the United shares as part of his controversial £790m takeover of the club, much to the anger of supporters.
At the end of the May, the board recommended that shareholders accept the £3 a share being offered by Malcolm Glazer for the remaining stakeholding he does not own.
Mr Glazer currently owns about 76.2% of Manchester United's shares.
It is thought that next week the Glazers will reveal their exact shareholding when all replies to their offer of £3 per share have been received.
On 16 May Mr Glazer said he had raised his stake in Manchester United to over 75%, finally gaining full control of the club.
The 76-year-old billionare is expected to delist the club's shares by 30 June, in a move that would end United's 14-year presence on the London Stock Exchange.
On Tuesday the club also said that Andy Anson had been re-appointed as club commercial director. He was one of the three directors that Mr Glazer voted off the board last November.
The appointment of some of his family representatives had been expected, with Joel expected to take on the most high-profile role.
Joel Glazer has worked as a vice president of First Allied Corporation, a US real estate investment company.
In 1995, he was appointed executive vice president of the NFL franchise Tampa Bay Buccaneers, owned by his father, and he still holds this position.
"He has extensive sports management experience," says a Manchester United statement to the London stock market.
Avram Glazer, aged 44, has also worked as a vice president of First Allied Corporation.
In 1995, he became president and chief executive officer of Zapata Corporation, a US public company trading on the New York stock exchange.
He is also chairman of the board of directors of Omega Protein Corporation, the Glazer family business which processes fish oils.
Bryan Glazer, aged 40, has also worked as a vice president of First Allied Corporation, and also serves on the board of directors of Zapata Corporation.
Like brother Joel, in 1995 he was made an executive vice president of the Tampa Bay Buccaneers.
