1. Ronaldo did not 'drag his team to the finals'.He scored the goals sure but the vast majority of his performances were awful.There isn't a single peformance which you would call memorable or was a "i was there" type performance. Players like messi, ronaldinho, zidane, ronaldo of brazil have many of these.
As an example in the 2016/17 UCL, he scored lots of tap ins (credit to him) but beyond that there really wasn't anything to write home about or last season where apart from the matches vs Juve he wasnt good at all in the knock out stages.He relies alot on his team mates' brilliance more than any other player considered to be a great of the game.In addition, i struggle to recall a single player who is considered a great having so many average to poor performances papered over by a goal or two.I personally was a huge fan of his,even stuck up for him when he was being called a one trick show pony earlier in his creer. But after 06/07 season and to a lesser extent 07/08 and 09/10, there has been a paucity of consistently truly great all round performances.
2.The Cruyff-muller comparison is apt.One was a fantastic all round attacking footballer,the other was essentially about scoring goals and he scored many and very important goals.Had muller been playing in this era of social media the 2 would be compared head to head just like cristiano and messi are without doubt.
As an example the el clasico this season.Everywhere in the media it was hyped up to be the first elclasico withour ronaldo or messi.But, has ronaldo ever been the stand out player in a single clasico or for that matter produced a truly great performance? there is non that i recall even in matches where he has scored the winner. The stats are quite damning and heavily skewed in messi's favour.
Messi: games played 38, won 17, drawn 9, lost 12, goals 26, goals to game ratio 0.68, assists 14, chances created 68.
Cristiano: games played 30, won 8, drawn 8, lost 14, goals 16, goals to games ratio 0.6, assists 1, chances created 15.
I rest my case.
