Atletico Madrid is not the title race. They're so inconsistent, and have no DNA to win the title. So i remove them. So i have only Barcelona / Real Madrid to win the title.

Gamblers are now only having Madrid / Barcelona to bet on winning the title, which much easier than before. I wonder why you called it not nice for gamblers. As far as i know, La liga has been the easist league to predict the winner after Bundesliga.
Atletico Madrid are still contenders of the La Liga title. The difference between the two top clubs and the Diego Someone side is just four points. Atletico can take advantage of Barcelona and Real Madrid in any game. The league still have more games to play, so all the top three teams have almost the same opportunity to win the trophy. Both Barcelona and Real Madrid are still playing in the UEFA which might affect their performance since they will play more games. Atletico can use the opportunity and gain more points..
They are less of contenders for the La Liga title, from beating Barcelona 2:0 to losing in the final minutes with 2 goals separating the scores. There are behaviors you see from teams that raise a second thought about whether they fit to contend among the best teams playing in the league. I don't want to say much to satisfy myself, Atletico Madrid may be in good form, but it goes past that if they want to win the title. Surprisingly Barcelona and Real Madrid, who still continue their fight for the Champions League may be able to pull more points than Atletico Madrid.
At the moment, Atletico may be claiming for La Liga title, in my opinion they will no longer be able to play well like Barcelona and Real Madrid. So maybe they will be able to win the title in the next season if they are able to try more hard than now. Maybe Atletico Madrid is not disappointed because they have to be promising to play more accurately in the future. I think a job may be honorable for Atletico Madrid, which is that they are able to include themselves in the top team during the La Liga season. However, they will be able to win in advance for the Barcelona team.
