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.
Although it is not certain but the club that Real Madrid will face in their postponed match is Valencia, a club that is currently at the bottom of the standings in the sense that this club is weaker than Real Madrid so there is no reason not to get the 3 points, Barcelona has clearly wasted a golden opportunity to continue to keep the distance with Real Madrid instead they continue to lose points thus giving way for Madrid to overtake them.
Btw regarding Lamine Yamal he has recovered and also played in the match against Las Palmas for 45 minutes and also made 4 shots but unfortunately Lamine Yamal could not help his club to win this time.
