I really have no idea.
Based on hearsay legacy, a look on his career and the available footage, I do think he should be among the top 1-2 GOAT.
But based on the lower football standard back in 60s, while he played most of his club football in regional league level (not his fault though as Brazil league was on regional format back then), I understand some people may rank him abit lower among top 4 GOAT.
But in any case, I think he should sit comfortably in the top tier (alongside Messi, Ronaldo, Maradona).
