I always found that a false economy, spending money and loads of it has only worked for the successful clubs, in large because of their ability to spend it again if those they spend large on failed.
We couldn't and still can't afford that level of mistake, so for all the hype and TBH I am excited with this season, the large spending on the 2 CM and CB have to work, for us they just have to.
For me its always been about the right player, not the right money spent in the grand scheme. BTW before anyone jumps on that and gets the wrong end of the stick, I am delighted we are securing the players the manager wants with the money and ambitions they are using to spend it, but they still have to be the right players, if they are then the money parted with matters not a jot
