With such a narrow points gap, it's bound to create a healthy rivalry between the two. Madrid are also trying to get up and Barcelona are trying not to let their guard down in their current position. It could be that Madrid cannot catch Barcelona because the remaining 1 match is still uncertain 3 points. Hansi Flick lost Yamal which made his attack a little blunt. Therefore, if he returns to the main squad Barcelona can immediately appear stable.
Real Madrid's current attack is also not as sharp as before because Vinicius is still injured so Hansi Flick actually doesn't need to panic about this even though Real Madrid still has one more match than the number of matches that Barcelona has played. And this week's match can also be very crucial if one of them cannot win the match because both will be guests at their opponent's home so both will definitely try to win in order to maintain the position so that it does not change immediately this week.
