So them buying potential rather than peak talent is folly whereas when we do it with the likes of Jones, Smalling, Hernandez et al, it's dandy? Let's face it, not every signing is going to work out every time but their approach to the transfer market since the takeover has been similar to ours, paying substancial fees for the best British talent around and looking for value where they can find it, and Adam for £10m or less, isn't such a big gamble in the modern day.
Bias as football supporters often influences our judgement too much, one minute Michael Owen was a joke and past it, next minute he signed for us and the old "will score us goals", "Fergie masterstroke" cliches were being rolled out. One minute Jordan Henderson had great potential, next minute he signed for our rivals, and he's complete pap who they've overpaid for. I could go on with the examples but the point is that viewing everything through red tinted specs isn't always the best way to come to a conclusion.
Yes, they probably overpaid on Henderson and certainly overpaid on Carroll but that's not to say they aren't good player's with further scope for development when taking their age into account. The same applies to us and all the young talent we pay a premium for, but the sad thing is that had Jones gone to Liverpool, we'd now have threads about how average he is, how Liverpool are mugs to spend so much on him etc.
