Precisely. Gus was good, but was pretty much lost the moment we went a goal behind. What was it - 40 odd games failed to win from going a goal down? Quite frankly a dismal record, and says a lot about his management style - that stat has continued at Sunderland. In that sense, it appears he is a bottle job and lacking in alternative tactics, something you couldn't implicitly suggest of Mullery.
Also, Creaky suggests Mullery wouldn't work with modern day football, probably correct - but Gus wouldn't work well with 70s footballers. Entirely different contexts, you can't judge it on that. Besides, football is riddled with managers who have won promotion from the third tier but proved fruitless elsewhere.
Fair enough if you're factoring in both contexts, the players at their disposal, the investment they received, etc. you're entitled to your opinion, but IMO, Mullery was a better manager, regardless of the way Gus left our club.
This and more.
Once we went a goal down with Poyet,that was it.
With Mullers,you were never absolutely sure what would happen,but it would be full of excitement and more often than not,a result ensued.
I know who I would like next to me in the proverbial trenches.
