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.
You are actually right if time is not taken ATM is going to occupy the first position in the La Liga table but the problem now is all of them are ( Madrid, Barcelona and ATM) are almost playing same thing i mean they are not even consistent in wining their matches, they will win today tomorrow or next they will lose or draw and it does not make sense but i strongly believe that this trophy is between Barcelona and Real Madrid. Real Madrid is at the verge of leading the table now and this will happen if only and only if they win their outstanding match and i want to believe or say that this opportunity can not pass them by the way i am seeing, it is not like i am certain about it though just my instinct and one thing i have noticed is that Real Madrid is playing like they are not complete or they can not do well without Vinicious which is very bad.
