If I'm honest, I'd rather Atlético de Madrid win the league this year or at least be in a position to win it until the end. I just checked and in the last 20 years 18 leagues have been won by either Barcelona or Madrid, and only two have been won by Atletico Madrid. A bit of variety for the title contenders doesn't hurt. Before that and in the early 2000s still won the title Valencia, which is not at all nowadays, and Deportivo de la Coruña, nowadays in the second division, so it all seems that the league is a matter of two and a third very occasionally.
Yes, in these two decades, the majority of Laliga trophies were won by Barcelona and Real Madrid. This is because both teams have very high quality players. So I personally am not surprised if these two teams are always able to compete for the Laliga trophy. But even so, it feels a little boring if for example only Real Madrid and Barcelona are always champions in Laliga. This also gives the impression that Laliga is not very competitive. So if, for example, this season Atletico Madrid becomes champion, I think that would be a very good thing. Because in the past few seasons Atletico Madrid has always finished in 3rd place in Laliga. So if, for example, this season Atletico Madrid is able to become champions in Laliga, I think this will be a very extraordinary thing.
But if we look at Atletico Madrid's current performance, I don't think they can compete with Barcelona or Real Madrid. So I personally think it will be a little difficult for Atletico Madrid to get to the top of the Laliga standings this season. Although the difference in points between Atletico and the top of the standings, namely Barcelona, is not too far at the moment. However, I think it will still be a little difficult for Atletico Madrid to shift Barcelona's position from the top of the Laliga standings. But if for example Barcelona and Real Madrid's performance declines, I think Atletico Madrid might have a slight chance of becoming champions in Laliga. But I think this is very difficult to happen. Remembering that Barcelona and Real Madrid are big teams that have a great way to rise from adversity.
