With Real Madrid's next match I think they will be able to win the match with a score of more than two goals, besides they can approach Barcelona's points who are leading the standings. Real Madrid's chances are very big, but we don't know what will happen later because anything can happen when it's on the field. In addition, they will act as hosts in this match, hosting Alaves at the Santiago Bernabeu of course this will make them more confident to compete.
Those who definitely want to lead the top of the standings will appear with their best performance to be able to beat their opponents, and with Alaves I think they will have difficulty winning this match to steal points from this match.

Real Madrid should not waste this match, 3 points are an absolute requirement to be able to continue to approach their rivals, and I am sure Ancelotti's squad can win this match especially since they are playing at home as you said, there is motivation to perform better in front of their own supporters.
On the other hand I will not underestimate Luis Garcia Plaza's team, they will work hard to at least steal points at the Bernabeu later,
we'll see tomorrow which club will perform well.
