There is not a chance Ronaldo will ever be considered to be in "that" category, alongside Maradona & Pele, IMO.
Those players all had a little something "more" in their game, compared to Ronaldo, who's sacrificed alot of his flair for ruthless efficiency (goals).
Also, the thing I hate about these "club" numbers that both Messi and Ronaldo put up, and it's another fact often ignored when compared to past greats, is that club level football is so skewed. They both have teams above anything else La Liga has to offer (their bench is often more expensive then the entire squad of their opponents), and both their teams are geared around getting the absolute best out of them both. Even the Champions league is a skewed competition. There are generally a handful of "great teams", but the rest are novice teams, with very small budgets.
The concentration of the world's best players are essentially stacked in 3 clubs - and 2 of them are Barca and Real, plus Bayern. In the EPL, you struggle to pick more than 2-3 world class players in the top sides, yet you look at those 3 clubs and every position is arguably stacked with the best in the world.
So yeah, i think their inflated "stats" need to be taken into perspective as well.
