Then there are other players who could easily have a claim that can’t be dismissed. I suppose the longevity of Messi and Ronaldo is why they will probably be remembered as the two best ever. They have dominated the Sport with one or the other always being the best player in the world since about 2006.
Ronaldo and Messi will only be remembered as the two best players ever primarily by millennials and people under 40. A lot of older people still rate other footballers as good or better.
There's an argument for Messi being GOAT I can buy (even without a WC), but there's absolutely none for Ronaldo. Ronaldo rarely if ever pulls off an assist like Messi did for Aguero's goal yesterday, Messi does those on a weekly basis for Barcelona ffs.
Ronaldo's game is much more limited after being a pure goalscorer. He's basically a more athletic version of Gerd Muller (who also scored 600 goals in 600 games). Ronaldo doesn't dribble any near as well as Maradona/Messi, his passing range is nowhere near as good as Zidane/Platini/Messi/Maradona/Cruyff, he's nowhere near a good free kick taker as Messi/Maradona. Arguably the best header of the ball ever though.
I would rank in the top 10 for definite, I'm not sure I'm rank him in the top 5 since I think there are better overall 'footballers' than Ronaldo.
Messi for me would be in the top 3 along Maradona and Pele, I think he is in the top GOAT tier since he can do absolutely everything on a football pitch like they both could.
