Yes, but not in the way you describe. Ronaldo's general play was the result of years of coaching, and it was just starting to get good. It would be strange to think he could play exactly the same way, or even better, in our team last year and without SAF's coaching.
Also, Ronaldo's style is absolutely nothing like Messi and Zidane.
Another strawman. I did not mention Ronaldo's style as similar to Messi or Zidane. I used them as an example of how player A being better than player B can make a team better, whether incrementally or significantly. I neither confirmed or denied that coaching would play a role in enhancing that increment or significant improvement further.
The original point was had the club built a title winning team around Rashford, he would be seen as a better player. Aside from that being obvious, my contention was at no point - even as a breakthrough 18-year old - has Rashford warranted having a title winning team built around him. Could he be a component in a title winning team? Sure, why not... he is a good player who can be very good. .
This debate - which I still cannot believe is happening - is focused on Rashford last season being as good as Ronaldo in 06/07. Rashford's season last year was the culmination of the coaching he has received. Ronaldo's was the culmination of the coaching he received. This goes without saying, but you said it anyway. Regardless, you are almost entirely ignoring talent and hard work, and the fact Ronaldo has more of both. Ronaldo was not "starting to get good" in 06/07, he was already "good". In fact, he was world class, he had been starting to "get good" in the seasons prior, although I would argue he was "good" even before United bought him. He was the second best player in the world in 06/07 and aside from participation in internationally important matches he was probably the best. All he added later was a more ruthless winning attitude and insatiable appetite for goals.
The problem is, looking at the culmination of coaching makes no sense. What are you saying, that if Rashford was given Ronaldo's coaching history he would be better, and Ronaldo given's Rashford's coaching would be worse? Well then yeah, maybe... but again it ignores any talent application the individual may or may not have.
