My first thoughts on this are that I don't quite know what to think! And this may sound obvious but I see it going either spectaculary wrong and disaster beckons or we'll some how get promotion and we'll all be living in dream land.
I'm hopeful of the latter as I suspect there's more money available than just the individual wealth of Riak..The new owner, as it's a consortium takeover, so I wouldn't be surprised if there's additional wealthy (very wealthy) investors!
Buying a club in the second tier of football that has the infrastructure to cope with premier league football and its rules about academies etc.. Costs a tiny tiny fraction of what it would cost to jump in at the deep end and buy a club already there and established. Putting into perspective, they've acquired the whole football club lock stock and barrel for probably somewhere near the figure the deal is worth for Man City to have bought James Milner!
So, to finaly make my point I think there may well be more money available than we think!
