Villarreal's victory against Rayo is very important for Villarreal, because right now Villarreal are struggling to get into the top 6. Moreover, Villarreal is
not usually able to win with a fairly large score. A big win against Rayo can at least increase the confidence of Villarreal players to be able to play well
in the next match. Even if they are lucky Villarreal can also move up to 5th position, but it seems difficult to expect Betis to lose in the last two games.
So the most realistic for Villarreal is to shift Real Sociedad who are in 6th position, especially next match Villarreal will face Real Sociedad, it will be
the deciding match for either Villarreal or Real Sociedad who has the right to be in 6th place.
