Realistically Mofakeng would be the type of player that moves to Netherlands, Belgium or even Championship. That's the kind of level and career progression he looks at from a spot judgement of that highlight.
But also a player like that has to be realistic too that Barcelona B would not be a bad option. Even Vinicius and Rodrygo started in Real Madrid Castilla to adapt, and there is way more to learn tactically at a club like Barca than to just get the ball, dribble and inshallah.
I know you don't rate him as highly as me, but I'd put Dani Rodriguez around the same level of Cordero. They are both guys who should be hovering around first team trainings while getting minutes in the B like Casado last year. While if the opportunity opens, then get first team call ups.
And on that note, from the little I have seen of Abdul Aziz, he should have played much more. Every action has shown potential- of the few he has had. With Albert Sanchez there though, Dani Rodriguez returning and Ibrahim arriving, I doubt he will get the opportunity and get signed however.
