Video: Sir Alex's era
Twenty-four years, one month, 13 days... those figures make Sir Alex Ferguson officially the longest-serving manager in United's history as he surpasses the reign of the great Sir Matt Busby.
When his tenure will end is anybody's guess but as Sir Alex himself says in our free video, any thoughts of him retiring have been pushed right to the back of his mind.
It seems that while he remains fit and healthy, and there are trophies still to be won - fittingly, his team are top of the league on this landmark day - the gaffer from Govan will stay at the helm. Congratulations, Sir Alex.
