Young players such as Yamal, Gavi and Pedri are a great advantage for Barcelona, which has a bad financial situation. If they sell them at the right prices, the club can become economically stronger. In addition, quality football players are constantly emerging from the infrastructure and by selling them, the club can earn additional income. Yamal is a good player, but I think it would be better for Barça if he brings a big transfer to the team.
There are important players that will be having good connection with the team's president and coach, such players will have lengthy years in the team and also selected in the best XI. Barcelona have quite vast numbers of talented players. Barcelona president, Joan Laporta will always show his concern for his team. He's not expressing moves to sell his promising young players, rather he will choose to stay calm and execute good budgets for Barcelona.
Barcelona players will be very tactical when they have Xavi Hernandez as headcoach, he's this type of coach that will not welcome the poor results because he's experienced and prominent for the team. Yamal Lamine, Pedri and Gavi have been the main players that have been strengthening the team's performance, always pushing forward for the good results, this is precisely the time for Barcelona to hold tightly on their players.
