He shouldn't be doing even that. Notice how Messi has behaved as a 'monk' for all his career. Never spoke, unless asked. While destroying everybody on the field. He's also Christian, who makes sign of the cross and gesture to God in heaven every time he scored a goal. He's the anti thesis of weak, money and fame driven guy, who does his thing for money. The true Scythian or spartan, Sure, he's incredibly rich, but that's not what driven him to become best. It's quite obvious that he doesn't even understand what to do with his riches as he doesn't care.
Yamal should take cues from Lionel, if he really wants to be one of the greats.
Being enslaved to merchants makes you a degenerate and weak person, which downstreams into complete collapse of your spirit. You become the aging degenerate like Ronnie (the Dinho, but actually also the CR7 in a way) did.
Messi is insormountable not only because of his skill, but because he is literal Hero of our times. The Achilles of Heracles as silly as it may sound.
