I think Barcelona players are just tired because recently they played so many matches with too much energy. So I think Hansi flick needs to take rest for them, like make a smooth tactic where the player doesn't use his full of stamina. But anyway Barcelona are still at the top of the league with 33 points. Let's see what happens next.
You are right. Barcelona has a very busy schedule. And Barcelona's players are now quite tired after consistently performing against big clubs. So Barcelona players need rest now.
Barcelona's defeat against Real Sociedad was completely unexpected. First Barcelona are in their best form at the moment. Real Sociedad, on the other hand, were not in good form. Barcelona were naturally considered favourites. But Barcelona lost the match 1-0.
I would say it was an accident. Because we saw Barcelona perform well in the whole match. However, I saw some very strong attacks from Real Sociedad players in this match. Barcelona would have conceded a few more goals if the Barcelona goalkeeper had not performed well today. However, despite the defeat in this match, Barcelona is 3 points ahead of Real Madrid.
