They could bounce back( I mean Barcelona) ... I didn't watch their last game but I watched the highlight later and I must say there was some serious biased refree judgement which is normal sometime.. though their performance wasn't as it used to be at the beginning of the league with their winning margin , but at the same time I think the coach is trying to test the squad with players shuffle imo ( I might be wrong though) though they seem to be missing some point I will only come to my final conclusion with their next game without neglecting the squad depth at the same time.
Do you think that the reason for their poor results is that Flick, now after a third of the season, decided to experiment with the lineup? I think it's just bad luck, they play just as well, they attack a lot, but they just can't score, sometimes it happens. And La Liga is not a league that asks for such mistakes, and now Real will most likely be able to overtake them, because they have a game in hand, and Atletico are within 2 points of them, and they are now strong enough to continue winning.
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.
