Real Madrid is still above Barcelona for now. With Real Madrid's composition so convincing, they are also made easier because they don't have to bother overhauling the game because most of them are players who have been in the team for a long time. While Barcelona of course must create harmony between players first.
I think some people are also aware of that now because it is clear that Real Madrid still has a good performance and also a very good strength so Real Madrid still has the potential to win another La Liga title. And what you said I think it's also true that Barcelona must create good cooperation within the team in order to get good results in every game this season.
