About some of those attributes you included.It's about consistency and a large sample size though, isn't it?
He's a very well rounded player in terms of attributes. That's not up for debate. Shooting, Dribbling, Heading, Crossing, Passing, Weak Foot, Strength, Pace, Height, Tricks n Skills, Penalties, Free Kicks, Long and super long shots, Mental attributes: he has it all?
Shooting? Messi has better conversion rate + better xG.
Dribbling already been settled. CR is heading GOAT. Crossing is a secondary attribute for inside forwards/false nine. Passing, Messi gets compared to the greatest passers of his generation. Weak foot, see below. Strength, Messi makes more use of his balance than CR does of his strength even though CR is stronger (again effeiciency?) same applies to max pace/acceleration. Rest, see below.
I asked about this once before but never got a reply.
"Ronaldo has this huge toolbox of being able to shoot from different angles, distances and with both feet. And more ways of beating the GK. Still Messi has more goals outside the box. What's more important? Being efficient or being spectacular?
In line with the ancient argument of Ronaldo being more 'complete'. Can score with both feet, can score with his head. No weaknesses really. Still outscored by this weaker, slower, [mental] midget who can only score with his left foot."
Also, yeah CR has more assists in this particular tournament CL, but you have to include the eye test as well. Nobody is going to say CR is a better assister than Messi just because he has more assists in CL. Pics below isn't to compare volume but to compare how the assists happen.
You're the one saying football is becoming more and more rigid. You of all people should love watching prime Messi play as it's pure joy. He's always taking the initiative to make something happen offensively. I can tell you all those times I've been at Camp Nou, only one player has the effect that lifts everyone's asses from the seats a couple of cm's whenever he has the ball. Can imagine that same effect occurs whenever CR's buddies are lining up a cross with him in the box. See the difference?
In terms of 'pure football' Messi is so incredibly superior to anyone else, not a lot of players can become MOTM with 0 goals and 0 assists for example and those who manage to do it sometimes are the ones you consider to be footballing artists. Eye test backs him, stats backs him, trophies back him.
