I didn't know that Forrest and McGregor weren't fêted much (unlike foreign players) by the Celtic support. I feel this is typical in Scotland. If you have an Italian, Spanish or sexy Dutch name, you're probably going to be regarded as intrinsically better. Likewise, if John McGlynn were a slim 30-y-o with a sexy foreign name, he would be praised as a tactical genius.
IMHO one of the best things Askou did was to show that humble players, Scottish or otherwise, could play great football based on ball-control, positional awareness, passing and moving, bravery on the ball and risk-acceptance if they are properly coached.
In a sense, Clarke is the opposite, as stuck in the past as the other hardy annuals on the Scottish managerial merry-go-round who people our media as pundits. As far as Scotland squads are concerned, OF Scottish players can walk in but players at provincial clubs are at a huge disadvantage and SC will look to the English Championship, whether in form or not, before considering a Watt, McGinn or Welsh.
Some might say Clarke hasn't as much time with the players as club managers do but most of those players outwith the Scottish Premiership are probably quite used to more enlightened coaching. They just need a mindset and a plan devised by a talented and progressive manager.
