Atletico for me is a synonym of a third team in La Liga. In last 10 seasons, they won one, been 2nd twice and had been 3rd the rest. There's no another name except Real Madrid, Barcelona and Atletico Madrid when it comes to top three. So, whatever the performance is, there's not really much pressure unless Atletico loses its third place. There have been some changes on Atletico I didn't liked like the departure of Angel Correa, Rodrigo De Paul and Samuel Lino all of whom had a great field presence. The offense of Atletico is still solid with Alexander Sorloth, Julian Alvarez and Antoine Griezmann but they need to work better on defense with the new players.
Yes, so far, these three clubs have been the most consistent each season in La Liga. The rivalry between Real Madrid and Barcelona is always fierce in El Clásico, and the two will fight fiercely for first place until the end. Well, this is true, because this season there have been quite significant changes at Real Madrid, including the manager. So, will Real Madrid reclaim the La Liga trophy, or will Barcelona retain it?
Now, we are also preparing to focus on UCL matches. Where they will also face top clubs from Europe. And Barcelona is quite an interesting match for the clubs they will face.
Source: Barcelona La Liga is always a tough competition between the top three teams and these top three teams are Real Madrid, Barcelona, and Atletico Madrid. Out of these three teams, in some seasons Real Madrid is seen at the top of the points table, in some seasons Barcelona is seen at the bottom of the points table, and in some seasons Atletico Madrid is seen at the top of the points table. As you said, the most competitive match in La Liga is the El Clasico match where Real Madrid and Barcelona compete and these competitions are always very interesting, although last season we saw a one-sided victory of Barcelona against Real Madrid, this season we expect of course we will see a tough competition between the two teams in the El Clasico match.
Now if we talk about the Champions League there too, but these two clubs of La Liga have performed well, especially Real Madrid.
Real Madrid has won the title a maximum of 15 times in the history of the Champions League, so Real Madrid must always be considered the favorite in the Champions League when discussing all other teams.
