Barcelona, Real Madrid and Atlético Madrid will be in the top three of the points table, it is absolutely certain. However, it is not yet certain which team will occupy the fourth place in the table. Real Sociedad, Real Betis and Villarreal are the three teams with equal chances to finish fourth in the table.
Villarreal is my favourite team for fourth place in the table. I think Villarreal has the best chance of finishing fourth in the table. Sociedad and Betis are ahead though. But their performance is not regular. Sociedad has won just one of their last 5 matches and Real Betis have won just two. On the other hand, compared to these two teams, Villarreal's performance is very good. Villarreal has won 4 of their last 5 matches. Villarreal can qualify for the Champions League if they continue with such a consistent performance.
Atletico madrid was able to keep their distance from the 4th ranked team with a wide difference of 6 points. I think their ranking will be safe enough for a while if they are able to maintain concentration in the upcoming matches. Rankings 1 and 2 are also unlikely to change as Barcelona as a whole they are the frontrunners for the Laliga title whereas real madrid they will maintain their ranking as best they can for the remainder of the season.
There is only strong competition in 4th place because Real Sociedad is not safe enough for them to secure 4th place because the point width with Betis is only 3 points, of course anything can happen if Sociedad loses in the upcoming matches
I think Atletico Madrid have a chance of competing with Real Madrid for second place in the standings, because Real Madrid are more focused on the Champions League, because in La Liga Barcelona are guaranteed winners. But if Real Madrid continue to play in the Champions League, they will surely make mistakes in La Liga, which could be a chance for Atletico Madrid.
