I read somewhere that Zeman will only retire when he dies, worth a go I reckon. Would be some culture shock for the fans and players I suppose.
Would tick most boxes:
Would make watching Villa entertaining.
Would set out to play football in a certain way and stick to it.
Would improve players no end e.g. Verratti, Insigne, etc
Would get players ultra fit.
Has to be attainable, he regularly takes on teams in lower divisions and I'm guessing would like to prove himself in England.
The defending can't get any more shambolic thus negating the one weakness in his sides.
