Gus
+'s = going from near bottom of 1st division to spl, staying in spl, national cup final.
-'s = aging and injury prone signing policy, short termism, not brilliant at PR with fans.
Danny
+'s = ability to sign players from lower divisions who don't look out of place in spl, good pr with fans.
-'s = three defeats on the trot to teams round about us (arguably though Gus did this more than once too)
Sir Alex
+'s = there must have been about 25,000 plusses
-'s = there must have been about...............ooops see what I did there
In short go through all of saints past managers and there will be plusses and minuses, surely all we care about is SMFC and wish them all the best at all times. I'd be sad if I thought a saints fan wanted us to crash and burn because the don't like the manager. After all though Gus was sacked he may well have walked (like Jimmy Calderwood) when he was told the budget for this season.
