Hard to compare players from different eras.
Imagine how good those players would have been with today’s coaching, fitness, diet, technology etc.
By the same token you could argue that those players had more to contend with because they got kicked and battered n a way that modern players would never understand.
Also, it’s hard to compare players like Ronaldo and Maradona because they’re totally different types of player. Obviously Ronaldo is far more athletic and driven than Diego but in terms of pure skill and trickery Ronaldo doesn’t even come close.
Same goes for the Messi v Ronaldo argument. For me Ronaldo is superior in many ways - physicality, determination, heading, power, pace etc. - but Messi has that ability to do things that nobody else can do. I remember reading an article a few years back that summed it up far better than I ever could - basically saying that Ronaldo created the exceptional player that he has become through physical development and sheer determination, whereas Messi was always naturally exceptional despite not having the physical attributes most players need to thrive in the modern game.
Personally I think we should just appreciate that we’ve been lucky enough to have two of the greatest ever players around at the same time pushing each other to be the best.
