"Even Messi lost the ball often" is argument on primary school level.
Hey, Lamine scores bangers. So what, Christensen scored one a month ago too.
Noone is disputing his qualities but let's call it like it is. Calling out particular mistakes does not take away from his obvious qualities.
Nobody denies Yamal loses the ball - the point is why. High-risk players always do, because they’re the ones constantly trying to break defenses. Messi was also sometimes criticized and had an enormous number of lost balls, yet it was precisely those risks that made him decisive. Using Messi as an example isn’t “primary school,” it’s literally the most relevant comparison- he also lost possession a lot because he was constantly trying to create.
Comparing that to Christensen randomly scoring a goal is a false equivalence - Yamal’s turnovers come directly from his role on the pitch. If you want a player who never loses the ball, you tell him to play sideways passes all match. If you want someone who changes games, you accept some mistakes as part of the deal.
Also, calling someone out for having a "primary school argument" because of your own inability to comprehend it is itself childish - or as you say it - primary school. Do better.
