You seem to be following Barca youth more than most here. What's your projection about this guy? Is he juxtaposed with Pedri much. Could he be like a better Pedri in terms of offense, allowing Pedri to settle in a deeper role?
You are giving me too much credit here
My rule of thumb is to not bother by prospects who are under 16, as they aren't even full grown into their bodies and a growth spurt (or lack of one) could change their whole body and their talent with it.
Lamina is 15 currently, and watching videos he looks talented among his peers, same like a guy like Endrick looked a year or so ago, tough to judge in both cases as those players are facing kids who might end up working retail jobs or engineering or whatever by the age of 25, while to make it in Barca 1st team you face the best of the best on regular basis.
Many hyped kids fell of a cliff after that cutting age of 16, I am not talking Halilovic or Bojan as those were still successful professionals, I am talking about someone like Teron (don't remember full name, as it is a decade or half ago) who was hyped as next Ayala from generation 91 and ended up playing in 5th division or so in Spain.
Now, after channeling my inner BBZ, I would say I am not overly hyped with Lamina as an upper end prospect so far. He feels more like a potential starting caliber player at best case scenario, a Di Maria type (if you forget about his goals with Argentina) who can be versatile and smart starting player but not someone you build your team around. Many think that Lamina might end up as interior while other think he will remain a winger. Tough to know and generally Barca has affection to those AM/Winger hybrids which rarely works but when it does it can give you an Iniesta or Pedri.
Don't think he should be doing pre-season with 1st team, he should be between Juvenil A and B team next year, and the former more than the later.
PS: Barca is interested in Estevao William aka Messinho who has Andre Curry as agent (ex-barca employee, Vitor Roque agent and a guy who was one of the engineers of R10, Neymar deals to join us) and as you may guessed a Barca fan, is the one I actually got really hyped from players who are U-16, he plays same position as Lamina (a left footed RW) and has great technique and explosiveness, he is a guy to follow and get hyped if he continue his trajectory tbh.
