Xavi seems to have succeeded in building his young squad better than Real Madrid. Lamine Yamal, Gavi, and Balde contributed to Spain, especially in international matches. This young player's performance is also good at club level so I really respect the way Barcelona builds their squad.
Not only that, Barcelona has succeeded in taking advantage of the transfer market this season by only paying very low costs. I can imagine Barcelona would probably be very strong in terms of squad depth if they had a transfer budget of 100 million euros this season. Barcelona and Real Madrid's rivalry this season is sure to be great, but I believe each of them will have problems to solve throughout the season.
Regarding Lamine Yamal, I think Xavi and Barcelona have long-term plans for this palyer and they want to keep Lamine Yamal for a long time, after the performance we saw from Lamine Yamal in season for Barcelona they know a player at this age in a gem in the market. Since Lamine Yamal is not 18 years old yet, they can expect his offer for only three years but his agent and Barcelona agreed to extend his offer for longer until he is 18 years old until 2030.
Lamiye yamal and gavi at the future assets owned by barcelona this time. It will be so stupid if xavi will be selling him to another club. He was still 16 years old and his performance already made many people feel amazed by him.
Barcelona was just finding another hidden gem from its academy. Yamal will be far better than gavi or even dembele which has been fully experienced as a winger.
I have expected him to be the same as neymar in the future. Neymar was a great winger and yamal has been starting his debut even when he was still under 18 years old.
Yamal has everything to become the next greatest player. He has good dribbling, shoot, teamwork, even everything.
We will see so many protests will come from fan if xavi will sell him to the another club. Yamal is staying at barcelona forever.
