I think Barcelona will win this match, Barcelona will not let Real Madrid get close. However, I do not think that Real Madrid will be able to catch Barcelona this season, many of Real Madrid's players have already been very disappointing due to injuries. Since Real Madrid will face Getafe in the next match, the betting odds in this match bring Real Madrid to win, but Real Madrid's current game is not very good. Accordingly, if Barcelona attacks strongly against Las Palmas, they will win and they will be able to move further up the points table. If you bet, Barcelona should catch this match and it will be possible to win here, Las Palmas does not have good defense and will not be able to resist Barcelona's attack.
We can't possibly know that yet, we can assume and I agree that it's looking more and more like Barcelona will win the league, they have few injuries too but not as severe and not to as many players and they come back quicker, like Yamal seems to be back soon.
However, we still can't be certain because Real Madrid is very close, which means that anything could happen, without Barcelona taking the gap higher, we can't really make a calculation yet, it's going to be close and undecided until we see some points lost by Madrid. In the end, they are Real Madrid and no matter how "bad" they look, they are always there, and they always have a chance to win games, even with their mostly bench team, they are still better than almost every other team.
