10. Man Utd sack Sir Alex in 1988
Back in 1986, Alex Ferguson was building quite a reputation for himself as a competent manager with Aberdeen - he led the club to three league titles and even European glory so it was never going to be long before he was touted for something bigger.
Replacing Ron Atkinson in November '86, Ferguson set about straightening out his inherited squad but failed to win a single piece of silverware until the now iconic FA Cup victory in 1989/90. Nowadays, this failure to succeed at such a big club would have spelt the end for the manager and if Manchester United had listened to the cries of their fans, things would be very different.
After two and a half seasons of misery, fans called for Alex Ferguson to be sacked, and then-Everton manager Howard Kendall was rumoured to be the club's preferred replacement. Had Kendall come in, Ferguson's squad would likely have returned to their drinking culture and depression would have set in amongst the group once more.
Kendall's style was in no way similar to Ferguson's attacking passion play and it is almost assured that United would've have fallen out of the First Division at the end of 88/89. A mass exodus of players would have ensued and you can all but forget about the Class of '92 ever breaking their way into footballing history.
