In 2005, the Glazer Family agreed to increase their stake in Manchester United, and in doing so increased their percentage of the club over the threshold required to constitute a formal takeover.
Since that point and even before their official takeover, United fans have been incredibly vocal in their opposition to their American owners, with protests in and outside the stadium being incredibly common.
However, it now may be coming to the end with the Glazer family announcing that they are looking at 'strategic alternatives' for investment, which could include selling the club.
