I think it's less straightforward than that. Smaller clubs have to do those deals through financial necessity. They are structured to achieve a certain level every year,sometimes they get a Ramirez and are able to improve 1 or 2 places before they make a big profit. If the cheap prospect fails, it's not big deal because the players are already there to achieve the goal. We can't do that because we don't have a squad capable of challenging for our goal, the Scudetto. That's why we have to pay big money, because our targets are higher and our threshold for failed signings lower, as evidenced by oour finishing 7th two years running.
Utd could afford to gamble on Chicharito because they have Rooney and Berba, we couldn't gamble on a Ramirez because we had a Pepe and Shartinez.
