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.
I think for this season Atlético de Madrid is quite realistic to win the title as long as Atlético de Madrid can be consistent and take advantage of Barcelona and Real Madrid's mistakes when they are down, as we have seen throughout this season if Real Madrid and Barcelona cannot maintain their consistent performance then because of that if Atlético de Madrid can continue to maintain consistency then it is very possible for them to win La Liga like they did in the 2020-2021 season.
