This " he doesn't know the Scottish game " pish annoys me, football is basically the same the world over, a 4-4-2, or 3-5-2 etc is the same in Lanarkshire as it is in Germany.
Honestly we could appoint Ancellotti , Klopp, Mourhino, etc and we'd get the same moans about not knowing the Scottish game, if that's actually a thing, it's Wimmers coaching, tactical, man management and football skills and abilities that matter, not whether he knows St Mirren are a bunch of thugs or Armstrong at Killie is a cheating wee fud.
