Klopp and Pep accepted, and Mourinho, Simeone considered of the last cycle, who else is out there who are destined to be managers for the ages rather than flash in the pan jobbers? What criteria constitutes a truly great manager for you, also? I think it's fair to say that not only are the aforementioned for this era winning, they are revolutionaries on top, which, for most people ticks all the boxes sans longevity and shoestring budget glory (the rise to the top). Pep probably qualifies for longevity and Klopp has the shoestringiness element to a degree, so in a roundabouts way they're both pretty much at the very top percentile in terms of criteria. Who slots in alongside them, for you?
