I think Real Madrid has not proven that they are now better because we have not seen the consistency of neat performance and also a combination of their two mainstay mbappe and also Vinicius.
They are smart players and can combine with each other after having enough working time in training and actual matches. If they can avoid internal conflict of interest, they will have very good combination and imagine that Mbappe, Vinicius and Rodrygo can make another trio attacking system for Real Madrid like Benzema, Ronaldo and Bale in the past, it's will be very powerful attacking system for them. Remember that behind these three players, there are Jude and Valverde who can score many goals.
Instead I think Barcelona this season must be recognized by all its changes and Hansi Flick as their new coach is successful enough to make a much better change for the performance of the Barcelona team even though they often cannot maintain their performance consistency.
Barcelona have more problems than Real Madrid because their players have less experience at top levels than Real Madrid players. They can change themselves season by season but it needs time and youth players can not help them winning La Liga title if they don't have enough experience.
Overall Real Madrid and Barcelona have a fairly balanced strength this season so that it is possible to occur in fierce competition in the race for the title, and the KUA of the team also has the same problem that is not able to maintain consistency so because it makes all possibilities possible for Barcelona or Real Madrid.
Overall Real Madrid are stronger than Barcelona and if there is no big surprise from either Barcelona with too excellent form or Real Madrid with too bad form, Real Madrid will win La Liga title in this season.
