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.
The Spanish league is a very strong league. I think everyone knows that. Even if you are Barcelona or Real Madrid, it is possible to lose points in that league. You can get some defeats when you least expect it. This is exactly what happened to Barcelona. No one expected them to get defeated on their home field. However, they lost 3 important points in the championship race by losing to Las Palmas. Real Madrid was of course the team that was the happiest about this situation. If they win the match against Valencia, which they are currently missing, they will be the leader.
