How many managers have left top division clubs in Scotland in the last 20 years for any other reason than failure ?
I know there are few exceptions, but in general, managers get fired or 'leave by mutual consent' 95% of the time. When I started going to games regularly, Willie McLean was in charge. he created a team that challenged the old firm regularly in matches, got conned out of a semi final win over the h**s and is largely lauded as the best team never to win a trophy. He was still sacked a couple of years later for a poor results, as have most of our managers since. It's the same for every other club. 90% of managers ultimately fail and get the sack.
