It will never happen, Ronaldo simply isnt in that mould which are usually referred to as greatest of all time. Pele, Maradona, Cruyff, Di Stefano and Messi, all these players share one thing in common - they are very complete attacking players. They could do everything and actually did a lot more than Ronaldo does over 90 minutes. All those players had great scoring ability and creativity but most importantly the ability to dominate a game by being at the heart of it the whole time. Ronaldo would always be in the bracket of the likes of Eusebio, Puskas, Ronaldo Fenomeno, etc, which isn't a bad company to have but the ones who would affect a game mainly throughee their goal threat despite having other qualities while the former group could assume most roles needed to influence a game and even if they don't score they would be able to tilt the game in the favour of their side.
Fair post. Agree with it as well. Though I think if he somehow leads Portugal to a WC win, it may elevate him in GOAT tier.
