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.
The conditions are still the same as long as there is a chance then anything is possible.
Madrid's start to the season was quite complicated where they lost momentum due to a performance that was not very good and this was due to several players being injured at the same time and indeed this was difficult for Ancelotti to anticipate even though he was experienced and already knew how to handle things like this but still it was not easy.
But talking about Madrid can catch up with Barcelona or not I think the opportunity is still there and even still quite large. Currently Madrid still has one game remaining and Barcelona is 4 points ahead, meaning that if Madrid can get a win in their remaining matches then of course 1 point gap is real in this case.
In addition, even if Madrid fail in their remaining matches, it doesn't mean that they have given up in the end because the season is still very long so I don't feel that they have lost and cannot make the competition more interesting for this season because of course halfway through the season there will definitely be some changes that occur.
