Next season, Real Madrid will also have a more fierce and fierce squad, so this will also prevent Barcelona from challenging for the title in La Liga again. Even though the facts you say don't rule out the possibility that Barcelona will be much better than this season. Because apart from there being still many young players in Barcelona, the team will also be trained by a new coach who may have new methods that will be implemented in the Barcelona squad later.
Real Madrid performance will go wild, actually,, because they really want to be ahead of every other club, especially Barcelona, and it is something they have always been achieving, they won two trophies in their own league and then the Champions League. i don't think Barcelona will get any better next season their is nothing new they have installed. The only person having the surprise here is not more than real Madrid, and that is because they are bringing in a new shipment. young players do not change anything, their point of concentration will be to be productive, because their is no use having players who are not productive if those young players are ready to rewrite history. look at the likes of Ronaldo Look at the likes of Benzema, that is the kind of players that every club will desire. if Barcelona wants to make it to the top, they have to be ready to work. but for now, people still have more faith in Real Madrid than in Barcelona, so their is no doubt that Real Madrid is still going to win because they are building up a force.
