Barcelona's current players are no less good than Real Madrid's, but yes, if you compare the two, Real Madrid looks better because they have experienced players and have a strong mentality to become champions, but if Barcelona succeeds in bringing in Nico Williams, I'm sure Barcelona can still do it. competing fiercely with Real Madrid because Barcelona's players have shown their quality at the Euros, so even though Barcelona is full of young players from their academy, they have been trained hard to become great players in the future.
I think everyone agrees that Real Madrid is the strongest team in La Liga and even in European competition at the moment. They managed to get Mbappe, which means they will again have a pure striker on the front line. And with Vinicius, Bellingham, Arda Guller, Camavinga and several other key players they have a big chance to win La Liga and even the UCL again. But on the other hand, in my personal opinion we cannot underestimate the young team from the Barcelona academy. Barcelona has many star players from their academy. Yamal and Gavi are examples of wonderkids from La Masia. But of course they still won't be able to compete with the experienced players at Real Madrid in the near future. But I think they still have the possibility to make a surprise this season.
Even though the competition hasn't started yet but I am quite sure that Real Madrid will become La Liga champions again because they still have the same foundation and it will get stronger with the new signings coming in. Barcelona may be proud of its young squad or even if Nico Williams takes part. But now the question is whether the new coach can maximize every potential that Barcelona has. Apart from that, there is still the biggest obstacle that has yet to be completely resolved because the financial crisis could arise again, and it could be detrimental to their players and make them unhappy if the solution is to cut their salaries significantly (like what has happened before).
