Barcelona still have the best squad in the Laliga now despite all the signings Real Madrid made in the transfer market. I can’t also count Real Madrid out of the race because they also have quality and world class players like Mbappe and Vini Junior, but their midfield and defense are not solid, they can’t win league with such weak defense and lack of creativity in their midfield.
For Alonso to enjoy his job at Real Madrid, the team need to sign good players that will benefit the team not average players or finished players from other teams: therefore, I am not expecting anything special this season.
It is true that Barcelona's squad is quite strong this season. But I do not agree with this that Madrid's defense is weak. We have seen Madrid's weak defense in the last season. But this season Madrid has added 3 talented defenders to the squad. Alexander arnold , Huijsen and carreras have been bought by Real madrid this season. Madrid spent 62.5 million for Huijsen and 50 million for Carreras. This is a big amount for any defender.
Madrid has tried its best to strengthen their squad. However we cannot say for sure whether Madrid will be able to play well. Still, Barcelona's overall performance is quite stable. Yamal and Rafinha are in good form as we have seen in their friendly matches.
