Looks nice for the most part.
Great that you included Xavi and Yashin.
-------------------------------------
And now for the inevitable nitpicking.
I would place Puskas and Xavi higher one tier and add Garrincha there as well.
Gerd Müller should be in the same tier as Eusébio as should *unpopular opinion incoming* Cristiano Ronaldo.
Not sure where to place Best, isn't his combination of spectacular ability, breathtaking peak performance and not-quite-fulfilled-promise extremely close to Ronaldinho's career?
From what footage I saw, Didi and Nílton Santos should definitely be included. Bobby Moore and Maldini might have a shout too, just like Iniesta.
(Lots of hearsay involved of course, since I'm not 70+ years old)
