Atletico Madrid still does not have immunity at their present spot, they can be displaced if they are not maintaining their winnings as they did in recent times. Anything is possible in football, and if they relax and Real Sociedad wins all their games, the situation will be the opposite. Still, Atletico Madrid has a better match for future success over Real Sociedad if their past performances are to be put into consideration.
The difference of 6 points from Sociedad and 9 points from Betis is of course comfortable for them to be in 3rd position. I think there is hope for them to stay in that position until the end especially seeing their rivals Sociedad, Betis and Villarreal are all still not will be able to overtake now especially Atletico are always in the best condition when the League towards the end of the season.
Now what I'm focusing on is actually not for the 3rd position because it will already be owned by Atletico but now the 4th position is still quite vulnerable and now we have 3 candidates who are suitable to be in that position.
