The points are still very close, and as long as the points gap can change their position in just one match, then it will remain a tight competition until the end of the season. However, apart from the advantage of still having a postponed match, Barcelona is also lucky because they have better goal productivity than Real Madrid, so that is capital for them if in the end they have to have the same points and they have to compete who is more productive in creating goals. Honestly, so far I still can't say anything, only that Barcelona is definitely one step ahead of Real Madrid.
Most of the players are now back to international leagues, matches wouldn't be available this week until next upper week from henceforth and what happened between now and then is how each player return back to their respective teams. I know for a fact that Real Madrid and Barcelona players will come back strongly but who is going to lose first is what I can't say but at some point, one of them will lose match for another, all of them can't win at once.
I'm no given up on Real Madrid yet until I see their next match, but Barcelona form is very impressive. The yesterday match they loss wasn't Flick fault. Many of their players are back to international match, I expect a good come back in their next match obviously and it's also possible that Aston Villa might want to make attempts to come back to second place if Real Madrid don't go fast because they are having the same points with Barcelona but there is a pending match for Barcelona.
