Poor Di Stefano. Much more important than cr for rm, can't even compare them.
Ronaldo is a better player than Di Stefano ever was. You can't find a superior aerial or long range player to Ronaldo, he is the best counter attacker in history. He is among the most gifted and natural two footed players. He was once a phenomenal dribbler, his passing is underrated as he is always a leader at Madrid in chances created and assists. He can provide creative and deadly decisive final balls as well as anybody who ever played. His contributions and productivity compared to Puskas and Di Stefano is off the charts. Ronaldo accounted for 20 of Madrid's 26 goals or 77% in the 15/16 Champion's League. His finishing, left foot skill, power, leaping ability, peak free-kick ability, passing, dribbling (trickery-footwork) and agility are all elite. I can admit Ronaldo has declined but his record is unprecedented. Ronaldo's average season at Madrid is 50 goals and 15 assists. Players like Zidane, R9, Raul Hugo etc. never achieved a fraction of what Ronaldo has accomplished.
Take into consideration the fact that Ronaldo has played with three/four entirely different sets of midfield attacking partners in just 7 years and you see how fast Ronaldo had to adjust and build relationships and chemistry with dozens of players without his production suffering. Ronaldo and Benzema have been the only attacking players that have lasted at Madrid. There have been close to 40 different midfielders in Ronaldo's years in Spain. This reality is never taken into the equation. I know other legends like Eusebio, Pele, Messi, Di Stefano etc. all had much more stability over their careers. There is no substitute for familiarity as evidenced by Spain and Germany's international results with the bulk of their team coming from one club. Portugal '66 was all Benfica stars as another example.
Here's a quick snapshot of the radical transformations in Madrid's line-ups, many players have come and gone so this is an approximation of the general lineups Ronaldo has predominately played alongside.
2009-2010
-------------------------Higuain/Benzema----------------
--------------------------------Raul--------------------------
-Ronaldo-------------------Guti/Kaka--------------Van der Vaart/Drenthe---
---------------------Alonso---------Lass Diarra-------------
2011-2013
----------------------Benzema/Higuain/Adebayor---------------------
----Ronaldo-----------------Ozil/Granero------------Di Maria/Callejon----
---------------------Alonso/Essien------Khedira/Gago-------------
2013-2016
---------------------------Benzema/Chicharito/Morata----------------
--------Ronaldo---------James--------------------Isco-------------Bale/Jese------
------------------------Kroos----------------Modric/Casemiro------------
Now in 2016/17 there is Assensio, Vasquez, and Lucas Silva. Chemistry obviously takes years to develop in most cases but what Ronaldo has done is nothing short of legendary. With all these different players he also had different managers with completely different systems and tactics. Barcelona managers employ the same system as the last where every player is groomed to play the Barca way. Madrid has no such identity and Ronaldo's performances never suffered no matter who was phased in or out. Messi has had some adjustments here and there from season to season but he has never had complete overhauls where this season's Barcelona bears little resemblance to last year's.
Di Stefano even said Madrid should pass his torch to Ronaldo and build a stadium bearing his name.
