I watch plenty of football ta, and I'd be more inclined to question your knowledge of the game if you think £40m for Carroll(£35m up front plus add ons)reflects his achievements and amount of top level football. If Carroll, a striker who has not even completed a season in elite football is worth £40m, then what on earth are established talents like Torres, Rooney, Tevez, Drogba, Anelka, Defoe worth? Dress it up all you like, it's shocking value for money and whether he becomes a top player or not, the fee is massively out of kilter with reality.
He is a kid with potential, nothing more or less. £40m is a disgustingly inflated price to pay. You can argue his age makes him a long-term investment but Liverpool will be lucky to recoup anything in terms of resale value. No way on earth will somebody be as daft as they were and spunk more than £30m on him in the future, let alone an improvement on the £40m they've paid.
