Okay. Please explain to me what you mean when you say this, "If anybody fails to realize that he isn’t as good as he is rated". Let's break this down a bit. How can you possibly compare how good a player he is with how much people rate him? What does that even mean? Can you actually give me a number from one to ten that describes exactly how good he is and then provide me with another number which represents how much people rate him?
If not, then what you're saying is absolutely meaningless. I'm not attacking you personally here. I'm attacking this general notion of people using this tactic to undermine players when it doesn't even make any sense.
In any case, Cassano is a superb player. I sometimes like to watch Sampdoria games just to see Cassano play. Maybe two or three players in the world of football can generate a genuine interest by me to watch them and he happens to be one of them. I don't understand what you have against him, but most people happen to think he's very talented and there probably is a good reason for that.
