Real Madrid have let go of their experienced players but they have brought in worthy players in their team so maybe we don't have to worry too much about how the young players will perform for Real Madrid. Recently Real Madrid's performance has been bad and the biggest reason behind this bad performance is the injuries of important players in their club. If those who have been trying to bring themselves back for one to two seasons can fully recover from their injuries and be ready to play on the field, then I believe Real Madrid will become a very strong team again. When Real Madrid performs poorly in a season, their tendency to perform well increases a lot so we can naturally assume that Real Madrid is going to perform better next season.
These are strategic and tactical issues that aim at a long-term reevaluation of the team.
Having all the players with a lot of experience is good in one way and dangerous in another. Remember, all older players are more prone to injuries. So They works for avoid this.
