What if Ronaldo had come up through Messi's path, and Messi through CR's?

Been thinking about this one. So much of the GOAT debate is about talent, but a huge part of it is the environment they grew up in.

Messi got La Masia from age 13, the perfect system built around him, the same club his whole peak, and a team of legends feeding him. Ronaldo came up at Sporting, had to physically build himself from a skinny kid into a monster, then moved country to country (England, Spain, Italy) and adapted his whole game every few years to keep scoring.

So flip it. Put a young Ronaldo in La Masia with that mentality and work ethic, in a system designed to make him the focal point. Honestly I think he breaks every record by an even bigger margin, because you're adding a perfect environment on top of the most driven athlete the sport has seen.

Now put Messi at Sporting, no tailor made system, having to survive the Premier League physically, then rebuild his game in three different leagues. Still world class obviously, but does he adapt the way Ronaldo did across all those moves? That's the part I'm not sure about.

To me this is what people miss, CR7 succeeded everywhere he went! Curious what you lot think, does Ronaldo in Messi's environment become untouchable, or am I overrating?
