The Glazer family have been in control of United since 2005 - and remain so, with Sir Jim Ratcliffe taking a minority stake in the club last year.
Edward Glazer - the youngest of the Glazer siblings - was asked about selling that minority share in a talk with students at the Kogod School of Business in Washington, he explained: "I think that... We're a family business, and it was really a decision we made collectively.
"Not every decision is six-nothing. But, ultimately, why we have been successful as a family business is that we've always kind of agreed that, if the majority of family members want to do something, we realise we are in a family business and we have to do it.
"One day it might be something that I'm in favour of. The next day, it may be something I'm not in favour. It was a family decision (the minority share sale)."
