First, Who claimed Heskey would be better than Hulk if went to Portugal? And Defenders who were hyped up in Portugal, Carvahlo, Coentrao, Ferreria, Silva, etc, they were labeled world class in Portugal. Those mentioned, are they not still World Class after their departure? If anything, their prestige got higher. Falcao is a prime example of his his talent just emerged in his first year in La Liga Everything stated still does not in the slightest support your argument in how sending a mediocre player to those leagues will make them perform better.
