I'm not so sure. I think the point is that there will always be well rated players that turn out to be complete wastes of spaces for whatever reason. Soldado, Torres, Falcao, Shevchenko, Marlet, Reyes, Rebrov, Robinho, and Veron to name but a few. If any of those players turned out to be successes, then a lot of people would be saying that no skill was required, but the point is that it is, even with some "established" stars.
Plenty of clubs were scouting Berbatov, Modric and Bale. But take nothing away from our scouts at the time who identified them and said that they would be successful.
