Yamal is one of the most potential players of Barcelona. He is getting often to score goals now. I think Barcelona management will regret it if they sell Yamal and they only get some money that never fixed the financial problem of Barcelona. IMO, Barcelona management should change their mind to sell the young players.
When other clubs don't have any good youngsters, La Masia graduates never end
And I think Barca doesn't want to lose Yamal, Pedri, Gavi, Balde, and Cubarsí.
They are part of the next generation. Barca cannot give up or let them go, they know the Consequences.
They are a good player with big prospects and currently mostly on low wages, there is no sensible reason to sell them, both sporting and economic. They are the future.
