He did miss of course they all do its the name of the game but that Spain game at that time Ronaldo was always the last to kick you can not compare that as he always did it just as he did vs athletic in the final. Messi took it missed ( which is fine it happens to the best) and then quit when he is the leader of that team and the "face" of soccer the "golden boy" Ronaldo record in the CL speaks for itself and I am not talking about the group stage but rather the knockouts where he absolutely obliterated every team up into and including the finals last year. As I said if Ronaldo is a 10 on the scale Messi is a 9.9 its that close but I'm taking Ronaldo all day he has that "aura" with him in your side you are that much closer to winning. As I said before in an era where people say Messi compares to the Peles and Maradonas of the world Ronaldo has been neck and neck with him the whole way through and as of right now? he is just that bit above. I will say again if Ronaldo wins the Champions league for the third time in a row adding to his Euro 2016 win this debate is well and truly buried. Messi would need a Monster World Cup to eclipse him.
That's because you're talking about stats, not football.
Ronaldo was a way better player 10, 8, 6 or even 4 years ago than what he is now, what did he had to show in silverware with Real Madrid?. Nothing close to what Messi had in the same era.
As I said and showed weeks ago, Ronaldo's stats in the KO round have gone ballistic in the last year, if you were to compare Leo at his age, against Cristiano at the same age, they were basically even in goals in the KO round. What happened is that one lost a generational midfield wonder duo in Xavi-Iniesta, and the other won it in Modric-Kroos, that's how Cristiano has been able to rack the amount of goals he has now while being less involved in his team game than in 2010 or 2012, he can delegate more, like Messi could do before.
But there's other things to the game, and midfield has always been important too (I'd even say the key part), the fact that Messi has kept his record in check with a top 3 all-time goalscorer while also being a much better midfield player is why he has layed grounds for the GOAT talk for almost a decade.
Anyone ever argued that Eto' was on the same level as Messi when he fell 2 goals behind in the treble season?, or that Suarez was a better player because he outscored Leo in 2016? RVN outscored Ronaldo, yet when the time of choosing between Cris and Ruud came, RVN had to take his bucket of goals and leave to Real Madrid, because even if no one at that time had realist expectations that Ronaldo would become a better scorer than Ruud, everyone could see that Ronaldo was already the better football player.
You can personally bury the debate anytime you want, but you're never going to bury the notion in most people minds that Messi is a better player than Cristiano, when it was the era of letting other players take care of the engine and be there to score, he did it at a rate better than Ronaldo, and when the era of taking the reins in midfield has come, Messi has done it seamlessly, he can keep banging goals at an absurd rate, on par with the best strikers in the world, while driving his team like a generational talent would do.
If you think that what settles the rivalry is that in their 30's Ronaldo ends up playing as a positional striker, Hugo Sanchez style, and Messi starts playing deeper in a Iniesta/Modric fashion, widening the gap in stats, not football, then that's your opinion, and your (and a big bunch of other people) agenda, but it's nothing definite.
