Real Madrid always chooses good young players to move forward and so that they can strengthen their club in the world. The players that Real Madrid currently has in their team are all very young players, but Real Madrid certainly needs midfielders and defenders, and the club becomes stronger with more experienced pressure. Although Real Madrid's current position in La Liga is lower than Barcelona, so if Real Madrid is to be better organized, experienced players will have to move to their team. The young players have not been able to adapt to the team that well, but if they can adapt to Real Madrid over time, they will be the strongest team. If Real Madrid can move experienced players to their team this season, the team may be stronger and they will compete in La Liga and the Champions League.
I think Real Madrid's young players have enough experience in every arena, they don't need experienced players to lead them anymore. You see, Real Madrid is looking to rejuvenate the squad, they are gradually purging the older players. Real Madrid just needs more unity from the stars. Carlo Ancelotti needs to find a solution, not the players, that is the responsibility of a coach when the team is in trouble.
Lack of minutes, that's what young player of Real Madrid missed. As per the latest stats, it shows that how Turkiye gave more minutes to the Arda instead of Real Madrid. That's being calculated since he joined in the Real Madrid. This is the main reason why the young player is late to evolve.
You told the truth about Arda's experienced enough and didn't need his senior's help. But, he lacks of minutes, that hurts his chemistry and mentality. Sadly, Ancellotti is still so stubborn not to play him regularly.
Even though Barcelona are in financial trouble, they still only use the players they have, they also use young players even those as young as 17 years old (Lamine Yamal). Barcelona is still stronger than ever. So why is Real Madrid, which always has a series of top stars, declining like this? The main reason comes from the coach's tactics.
Barcelona did it, and because of their financial issue. Their financial issue forced them to use academy players, but heir plan worked well. It's kinda different with madrid who always put their young players sit on the bench.
