As good as Ronaldo has been for us, and how good he still is, he is not the best player of all time, though he is certainly up there in terms of consistency and the impact he has.
I would argue top 10, simply for sheer consistency and impact, but his abilities on the ball are too average to be a top 3-5, imo.
But thats neither here or there, saying you are "the best player of all time" is just disrespectful towards many other legends of this game, and you come across as kind of a twat by saying it.
But we all know Ronaldo is an egomaniac, he just loves himself so damn much, thats how it is.
