With the way the La Liga table is moving, I don't think Barcelona will favor any team currently because if they mistakenly draw or lose, Real Madrid will top the league again, making it difficult for Barcelona to have the opportunity to top the league again. I'm not sure if your opinion will work because Barcelona don't usually score small goals in my opinion, and they will even play more than 3.5 goals if they don't play in the game, that will definitely be a good win tonight for Barcelona, because I Notice sometimes Barcelona usually draw against small clubs and that is making madrid top them in the league, because seriously speaking Barcelona are more better then real madrid this season, and if they meet again he will be hard if Barcelona didn't defeat madrid for the third time, except madrid as improve then before and making it difficult for Barcelona to break there line. Let see how Barcelona will play against Las Palmas and see who will get three point home tonight.
In my opinion, it is too early to judge that Barcelona is better than Real Madrid in this season. There are still some good match ahead for both teams. Actually Real Madrid is suffering specially in defense line. They're recovering from it and I hope they'll try to secure the top position of table again by beating Barcelona.
Up until now, both teams have had scenarios where they were good and bad. We can evaluate Barcelona's superiority over Real Madrid in their one-on-one matches separately, which is why many commentators see Barcelona as better. However, they are currently very close in terms of points, and I think it is a bit early to say which one is better.
Barcelona is currently playing with Las Palmas, the first half is almost over and there has been no goal in the match yet. Barcelona will press more in the second half, they have to win this match. Hansi Flick will tactically want them to score goals, so it is a setup accordingly.
