He just reads the game really well which is the first thing you have to be impressed by for a debutant central defender. We see the young kids perform higher up the pitch where you aren’t as vulnerable to being punished by errors. So while the composure is obviously something we see in a lot of the young La Masia players anyway, it’s even more than that - his positional awareness, coupled to forward passes to evade pressure & start attacks - he had a direct hand in 2/4 goals
Defensively, his phyical tools are obviously more impressive than Eric but its the interventions he anticipates so consistently that is mature for a player of his age. I think there was one moment where he wasn’t in the right position throughout the match, on Mayoral’s late chance otherwise he was the key ball distributor on a day where the team continued to struggle dealing with the high press. Won every duel he had making a formidable pairing with Araujo in the center of defense
Pau ended the match failing to make a single error - his passes appear to have the potential to be a great weapon when you expect to see that more from a DM, or say a young Pique. Better still than the improvements we are sure to see physically and tactically in a player a decade away from his prime
Probably grows taller than his current 1.85 too
