I guess it's only an investment if it works and you go up and stay up. We invested when we last got relegated and it didn't pay off. Lots of teams have spent big including us over the years and it doesn’t pay off.
Luton have gone up without spending anything like we have, those players didn't want to play in the championship, why would they when they can play in the Premier league, even if only for one season initially or play for a well known European club.
I would say MC blew the best chance the club had of promotion last year, it was in our hands, we lost momentum at a crucial time and rolled over to Coventry in the home tie, yet SG gets the blame.
