In addition to Real Madrid's front line which is no longer functioning optimally this season, Real Madrid's young players are also not often relied on in every important match so that they also cannot make better developments in the current Real Madrid squad. And currently Barcelona continues to make progress through their game in any match until they are able to create an extraordinary distance with Real Madrid in La Liga this season.
It makes no sense to rely on young players in important matches when you have all the star players you need in the squad. Coaches can rotate one or two main players with young players, but they will only do so when the team is leading the match with a score that is considered safe so that the risk of defeat can be minimized. Ancelotti or especially Real Madrid are not used to relying on young players, so don't expect to see them playing big matches with such a young line-up.
Barcelona has made progress as expected, but it's clearly not just about this season. Hansi Flick has fixed Xavi's shortcomings for Barcelona so far, so Barcelona under him looks better and more consistent. However, some things might be different if Hansi Flick got his main player injured, this could affect the team's performance. But fortunately, so far Barcelona has created a fairly safe points gap from its toughest rivals.
