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.
Real Madrid and Atletico Madrid are both aware about the level of consistency, they will always push further inother to accomplish their goals, it doesn't settled down with them. Barcelona headcoach, Hansi Flick and his club messed up the first time and that spell out bad for them but I don't think they will get intrigued again because they've found a formidable foundation. Barcelona players developed a good chemistry and this feature is helping them win tough games and moving towards winning titles this season. They just need more time to set things in place for triump.
