This is one of those comparisons that will not die for a while. It's like comparing Kobe Bryant to Michael Jordan. People get in heated arguement over them. If I were to select one of them, I will take R9. There are too many reasons why I would take R9 over CR7, but I will only state one: the defensive players when R9 played were deadly and guess what, he still dominated. Now, if you are not old enough to have seen R9 play throughout his career, maybe some youtube clips might do justice but that doesn't tell the whole story. Please, selected one of the two players and make a logical arguement as to why you selected the player.
