Looking at the rankings of managers in the last few pages of this thread, I find Billy McNeill criminally underrated. Took over after we went down in 1983. We'd lost Corrigan and Cross before the end of the previous season, then several players left in the close season. We were absolutely broke, and could easily have struggled in the second tier in the way we did after taking the drop in the 1990s. That we had one season where we finished one place outside the promotion zone, then got promoted, then stayed up in McNeill's three seasons in charge was an outstanding feat of management.
Yes, a lot of the football was poor and some players we bought were dreadful, but that was a function of the financial constraints he was operating under. Blues dislike the fact that he walked out on us to join Villa, but I don't blame anyone working for that abject, despicable and mendacious **** Swales for seeking a way out.
McNeill certainly isn't the best manager we've had (Pep is) but he belongs in the top ten.
