WHO IS THE GREATEST CITY MANAGER IN PAST 20 YEARS ?

No brained really....... Malky Mackay in my lifetime

If you asked me that question exactly twelve months ago I would have said Malky Mackay, without hesitation.

As things have come to pass since then, I do feel that, with all things being considered, that Dave Jones given the same funds & resources could have achieved the same Premiership promotion. We will never know!

Dave Jones for me, worked under very tight budgets and made the club alot of money in player sales, I was a bit too young to remember the Eddie May era properly

This is not an easy one to answer.
One is coloured by the resources each manager could draw upon to produce results .i.e. money and this varied from a lot less than nothing to just a bit over nothing in the main.
All in all, whilst I stopped backing him toward the end(he stayed too long) I would nominate D Jones on his record.

Dave Jones everytime for me.

For me it's Malky Mackay

Yep.

Malky.
