Some will get angry for this, but it seems that Yamal talks way too much and drains his emotional batteries easily.
I know, he is a kid.
But for now, he is too emotionally invested in some matches.
A few weeks ago, when we won against Real in CDR final, I have seen some comments from him like "no matter if we are 0:3 down, we will win. No one can beat Barca this season."
10 days later we were litterally KOd in the most important matches of the season vs Inter, and he played with way less motivation than vs Real Madrid.
In Nations League, the same.
When it was Yamal vs Mbappe (Ballon D Or battle) or Barca's star vs Real's star, he was again flying on a field and played awesome.
But, the same as against Inter, it seems that he has drained all of his motivation vs Mbappe.
And today, he was again way below his level.
And his team lost again.
He was a non-factor.
I know, he is just a kid.
His attittude will probably improve.
But for now, we can count on Yamal in big matches ONLY if we didn't face Real/Vinicius/Jude/Mbappe a few days before the important tie.
