It took several years for Fergie to win a thing at Man Utd. It’s a good job they didn’t listen to RedDevil414 demanding he should be sacked in December 1986 because he’s a simpleton incapable of learning anything* and won’t change his playing style through arrogance.
*Granted, Fergie had pedigree in the Scottish league at this point, but RedDevil414 would be reminding those arguing this by saying there’s a world of difference between the English and Scottish leagues.
