Barcelona is in a situation that looks really disappointing, maybe they will not be able to hold on to the top spot until the end of the season. Barcelona lost the match at home against Las Palmas.
I read Flick's interview after the game and it seems he believes that his team is not clinical enough[1]. I also saw some tweets blaming Lewandowski because he lost possession too many times and failed to convert good goalscoring chances into goals. Whether it was his fault or not, I do agree that the team needs to improve their chemistry on the pitch so they can create more chances. I guess that happens if you don't have a good backup.

https://barcauniversal.com/hansi-flicks-scathing-assessment-after-barcelona-lose-1-2-to-las-palmas-this-is-our-problem/Barca's defeat at Camp Nou against Las Palmas has received attention from various parties, especially losing full points to an underdog team should not have happened. However, this is football and I'm sure Flick is very aware of this result. Referring to the link you shared, I agree with what Flick said after the match ended. He talked about the team's play and the chances they had, unfortunately his team did not play much better. Moreover, it seems that Flick is trying to rotate some of his players, with the scenario that they have a busy schedule. We can see Flick preferring to play Lopez and Torre in last night's match, unfortunately these two players could not play optimally. Flick did not even play Olmo, even though if he was given the opportunity to play as a main starter, the results might have been different. Even worse, Barca lost one of their defenders due to injury. On the other hand, Barcelona's defeat in last night's match made Atletico narrow the points gap between the two teams. Today Madrid will host Getafe, of course Ancelotti will be looking for a win to narrow the points gap from Barcelona. Well, let's wait.
