What exactly do you mean by this? If you're implying that he had to work harder than Messi, Zidane, Brazil Ronaldo to achieve his current status as one of the best ever players that's nonsense. I think this is one of my biggest pet peeves in football that Cristiano has an aura of having to work harder than everyone else because he wasn't born with the god given talent the other elite players were, and had to build his body to perfection in order to perform. Cristiano has that god given talent and works just as hard as the other tier 1 players, but that doesn't mean the other players didn't work hard and simply became the best just by waking up and walking to the pitch. Take Ronaldinho for example. Why did he so suddenly fall from his mantle as BPITW to the Mexican league? He got complacent and didn't work hard. When he was at his peak, it was a combination of work + talent. Same with Ronaldo. Same with Messi. Same with Cristiano. The notion of "self made player" means nothing. Just because Ronaldo is a player whose image seems attainable ("oh he's good only because he has a greek god body") and most agree that Messi's game is hard to imitate, does not mean Ronaldo is a "self made player". They are both self made players. They were both blessed with innate gifts and the desire to work hard; you cannot quantity one had/did more than the other.
If you didn't mean this, I apologize for the rant
