I think the Villa situation, at the time, put the fear of god into tightwad Jenkins and he changed the combination to the safe!
This left Darren with few options, with regards transfers, so he has used his nous and brought in players with experience to bolster the squad. The likes of Mears and Hoolahan will do a job over the season (as proved on Saturday), provided they are only required as cover. If we do get hit by injuries then we could be found wanting but we would have to be very unlucky.
The problem will come if we get promoted, we lose key players and our already ageing squad is a year older. It's a Catch 22 though, if you do a Villa and spunk a load of money at it and don't go up, you are in financial meltdown but, if you don't spend and do go up, you need a complete rebuild.
Darren may have preferred the former but it's not his call so he's towed the party line and I think he's worked an absolute miracle under the circumstances and long may it continue.
