The Glazers have put another 9.5million shares in Manchester United on the New York Stock Exchange - worth US$186.86m (£137.12m) - although a statement makes clear that the club 'will not receive any proceeds from the sale'.
United supporters have endured a tumultuous relationship with their American owners since their 2005 takeover of the club, with frustrations reaching a boiling point five months ago with the formation of the European Super League.
Co-chairman Joel Glazer was at the heart of the disastrous plot to shake up the football landscape which triggered huge backlash from fans, ex-players and Prime Minister Boris Johnson.
