It's certainly not only Pele, or even Maradona.
Try a google search about older players and you will find many names.
Try on youtube then to see videos of them.
It is not posssible of course to make an opinion with the same standards of the nowadays players (that you can see them every week playing) but its the best you can do.
Football, like movies, music, literature and everything else in life is an eternal situation!
With past, present and future!!

Zizo is the greatest according to my view, Pele played in time there was no off-side in, and his legacy about 1000+ goals, i believe they count even the goals he scored when playing in street, Maradona is greater than him a bunch but also we was playing in old times where the rules were different, but he drive Napoli into the glory, for both Messi and Ronaldo, once they bring National cup to their countries, then i can consider them as the greatest
