Ronaldo's uniqueness is his relentlessness. A lot of players can read the offensive play, but not a lot, if any, have the drive to be there every single time. It takes a lot physically and mentally. There were games in his prime where he had 15 shots a game.
But there's also a downside. He's not a very good finisher. You can check the stats. He's the most wasteful striker in Europe this past decade.
Meaning, you need to create a lot for him and you'll get your goals. It'll take years to transform Juventus to suit Ronaldo.
We're talking about not only changing players (The Matuidi's and the Khedira's), but also changing the culture of the club.
Funny as it sounds, his best scoring season for Juventus will probably be when he's 37/38.
