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.

Xavi good plan when finances were unstable chose to retain young players from academics who had excellent talent and were trained from an early age to continue to improve the quality of their matches and improve their good performance to continue their career with Barcelona with big names that could be known throughout the world. maybe I am exaggerating, but seeing the appearance of this young player I am reminded of the playing style of some of the great players who have played at Barcelona and hopefully Lamine Yamal can become the next big player.https://www.forbes.com/sites/tomsanderson/2023/09/10/fc-barcelona-and-lamine-yamal-agree-seven-year-contract-extension-plan-reports/
Xavi plan will make Real Madrid jealous, who at that time recruited young player Arda Guler but unfortunately he could not appear on the field with Madrid due to an injury that had not healed.
