I think Atletico Madrid has no chance to compete for the title anymore. Only Real Madrid can compete for the title, but they must beat Barcelona in the next El Clasico and win all the remaining matches. So, we only have 2 teams that join the race for the title.
Barcelona has performed consistently again. If you remembered they ever played inconsistently during this season. That's why Real Madrid could overtake them in the 1st place few months ago. Luckily, Barcelona has found out their winning mentality anymore. Hansi Flick is successful to improve the players' mentality and set better game styles.
Atletico Madrid remaining 9 points left from Barcelona and small chance for winning La Liga trophy in this season, but have 9 matches left depend with Barcelona and Real Madrid matches result keep consistent secure three points or not. Considering 9 matches left in La Liga, Atletico Madrid not face any top standings team except Real Betis at last games week if can secure all three points matches left actually still have chance if Barcelona and Madrid losses points.
However, Barcelona and Real Madrid are favorable team for La Liga tittle race in this season both teams remaining 3 points and face each other at El Clasico match next month, still difficult for predicting which one team closer to be the winner although Barcelona leading the top position with 3 points left but Madrid still have chance if can beat Barcelona at games week 35.
