It's still early in the season and there's still a lot of time for the teams to improve, Barcelona currently looks weak in terms of defense but Real Madrid also has problems in the front line, in the last few matches Real Madrid has had quite a hard time scoring goals.
So I think these two top La Liga teams have different problems now, but how these teams can handle them and get out of these problems will be profitable for them to be able to chase the title this season.
Barcelona was really worried in the match against Villareal where currently the quality of Barcelona's defense is having problems. Barcelona conceded 3 goals in that match, which also indicates that there are problems that need to be fixed in defense. Meanwhile, in the next match, Barcelona only conceded 1 goal against Osasuna and in that match Barcelona's defense looked quite good.
Barcelona has a good right-back at the moment, which is definitely useful considering that so far Barcelona doesn't have a good right-back. Cancelo and Balde will likely be the main choices in most matches, while Araujo (currently still injured) and Kounde will play as central defenders. This could solve Barcelona's defensive problems, but Barcelona must do it carefully.
