I think it's been more of a case of putting round pegs in round holes, or in other words playing a formation that best suits the players available. I'd say there are two methods that dictates how you play. The manager sets his formation and tactics and builds a team based on it or, especially when you're limited in terms of the players at your disposal, you implement a system that best suits the players that you've got. Wilder quickly realised that he couldn't play his favoured 4-4-2 with the players he'd got so he reverted to 3-5-2 (or 3-4-1-2) to suit the players, and hats off to him and Knill for having the balls to do it and making it work.
I'll be interested to see what happens in the summer and what formation we'll be playing at the start of next season. Will he recruit to play a more orthodox 4-4-2 or will he now stick with the 3-4-1-2 that has worked so well. I suppose the key is to have a squad of players that can adapt and play just as well in any formation. Without wishing to go off on a tangent about it, I think we'd need to sign a very good CB to play 4 at the back and possibly a defensive midfielder enforcer type at the very least.
