Who are they? Well, just about any football team with a red jersey has a chance of being dubbed the Red Devils – apart, maybe, from Liverpool, who’d be a touch reluctant to share a nickname with their beloved rivals from down the road.

The Belgian national side, for example, is known as Diables Rouges or Rode Duivels, depending whether you speak French or Flemish, with teams ranging from Korea to Kaiserslautern, Congo to Hapoel Tel Aviv (The Red Demons, to be exact) and Turkish club Bulancakspor also carrying the tag.

Manchester United: It was Matt Busby who ordained that United be known as the Red Devils in the 1960s, as a new nickname was required after the loss of so many of his Busby Babes in Munich. The local Salford Rugby Club, who played in red shirts, had been known as the Red Devils, a name that appealed to the manager. The devil soon started appearing on scarves and in match programmes, and, in 1970, was incorporated in the new club crest (along with a ship, a reference to the city’s trading history through the Manchester canal).
