Because there's a reason these guys ended up being GOAT's in their respective sports, especially in football which is the most universally played sport on earth. If you have some margin sports, there's a reason someone else might sneak up the spotlight than the most "talented" one, but when we're talking about football, with all the players playing around or who had played before, there's absolutely no way a GOAT can be less talented than a guy, who isn't even considered as a top 20 of all time and most likely, won't be. There's so many people who tried, so many people who are trying and it's the most applied profession in the world by far which means, most competitive thing to "apply" and yet, some of the people saying that Ronaldo isn't the most talented because he has such a good work ethic. Im sure there's millions of players who are doing whatever they can to accomplish what Ronaldo did, yet nobody can get the results even with the same training regimes, neither would Neymar because A. He isn't that good of an athlete, B. He's way more injury prone and C. he won't have the same mindset so even if he had more "talent" by having ball on his feet than Ronaldo did, it doesn't make him more or equally "talented".
People claim that Messi is way more "talented" than Ronaldo is, which is another thing which is funny. If someone can explain how he is more talented, i'd like to know. I can just say that you could look at the height, athleticism, physicality etc. to have a glue who again, is a better athlete. If we weren't talking about sports, then being a better athlete wouldn't matter. Messi might have naturally better ball control and such, but since game ain't all about that, it just means that he isn't more "talented" but maybe one part of the game. If football was all about crossing and heading the ball in, Messi wouldn't even be considered a player but since it ain't all about that, it doesn't matter. We are talking about the most played sports on earth, with certain physical demands, with certain skill set and so on and if you combine all of that, you get the best player out there and for the past 10-15 years it has been Ronaldo and Messi, as they're the most "talented" players of all time and it's not even a question and bringing Neymar's name there is just an insult.
