Think it was Strachan who said that Celtic now can't match the wages being paid by Hull City, which gives their financial clout some perspective.
Mowbray would be a good manager for Celtic - used to working within a very tight budget, likes his teams to play attractive football and has had relative success with the Baggies. Might be a decent sideways career move for him as Celtic offer European football which would add to his CV if he wanted to get a bigger job afterwards.
