Good on him. Credit for wanting to test his ability at a much harder level, rather than the easy option of pissing the SPL every season.
I admire the bloke all the abuse he has had over the years bullets in post been attacked by supporters in dugout all because of religion and stuck by celtic not suprised he wants another challenge though
That's football for you. Do something that any man on the street could do in his sleep and earn yourself a job at the equivalent of a top FTSE company safe in the knowledge that when you fail your pain will be cushioned by the massive payoff you will get. Then just move on to another club and the whole merry-go-round starts again. You have to love football, the only industry to make millionaires from poor performance.
