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.
The problem is the level of consistency of Atlético Madrid, we also have to see because Atlético Madrid can still be defeated by other teams in La Liga this season, but if from now on Atlético Madrid can continue to win and not experience defeat again in the upcoming matches, of course Atlético Madrid can have the opportunity to occupy first place and even win La Liga this season if Barcelona and Real Madrid do not improve in the near future or at least when the transfer market reopens early next year.
After Madrid and Barcelona have dropped key points in some of their matches, of course that it provides an equal chance for Atletico Madrid to be title contenders this season, so far we see that Barcelona, Madrid and atletico are competing closely to dominate the top of the La Liga standings and the three are only separated by a very small point difference at the moment, Atletico have great potential to win the La Liga title if they can maintain their current consistency, as so far they have a strong squad with the likes of Griezmann, Alvarez and Sorloth being a threat in opponents defend line, but their main problem so far has been consistency, so if simeone will have to solve that problem if they want to compete with Barcelona and Madrid until the end of the season.
Despite losing their previous match and allowing other strong league contenders like Real Madrid and Atletico Madrid close the gap on the table, I think Barcelona are very strong contenders just that they need to put in more effort to be sure the win the league. I don't see the possibility of Atletico Madrid winning the league it's normal for them to try as much as possible to maintain the top 3 or 4 but winning the league still remains between Barcelona and Real Madrid, well anything is possible let's see if Simeone would suprise us this season. However Barcelona would be playing against Mallorca today as the visiting team, they lost their previous match so I don't think they'll want to lose this one as well, especially now that their rivals have closed the gap, the threw points is so important to Barcelona and I know they'll do everything possible to get it against Mallorca.
