While a Reds player has netted three goals or more in a game on 224 separate occasions, it almost goes without saying that hitting six is an exceedingly rare event - Harold Halse, in the 1911 FA Charity Shield, is the only other man to have managed the feat for United.
The achievement is even more incredible when you consider that Best was returning from a 28-day suspension.
As the man himself said after the match: “I’ve been living in secret fear we’d lose this game, especially with me back!”
h Best had to wait 20 minutes for his first goal, a header from Brian Kidd’s deep cross from the right.
