It's not how much you spend, it's how you spend/manage it.
Football is littered with teams that spent vast sums of money trying to win titles and trophies yet couldn't.
Signing players that will be successful is such a difficult thing to do.
Even the best managers like Ferguson have got it spectacularly wrong at times.
Clubs can do all the research but often luck comes into it.
We signed Naughton & Walker at the same time yet everyone at Sheffield Utd thought Naughton would be the better player.
No one predicted what Bale would develop into.
When Salah went to Pool I dont recall anyone expecting that much from him but pound for pound he must have been one of the best buys in recent history. Everyone thought they overpaid for VVD but it looks like a great investment now. I miss the days when they signed talents like Andy Carrol.
