its not your money mate, dont worry. Theres paid professionals at the club whos job it is to concern themselves with the monetary aspects of signings, the board,rom and the manager discuss transfers and buy, based on many factors, players they think worthy. If we spend 50 mill again on Cavani that is not a given that he'll flop nor is it a cert he'll succeed but we shouldnt not spend through fear of him having a mare! Picking up gems for nout and transforming them into multimillion pound superstars obviously is a brilliant way to work and extremely idealistic but theres absolutely no guarantee that the players you pick up will go on to be anything. Everything is a gamble, some you win some you lose.
