It doesn't seem like Barcelona is sacrificing domestic performance for glory in the Champions League because in the Champions League there are still many strong teams where it is still not certain for Barcelona to be completely successful. So Barcelona still has to play quite seriously in its domestic league so as not to be far behind some of its rivals there, but what has been seen so far is the actual reality which is not a deliberate sacrifice by Barcelona.
Of course, for Barcelona, Laliga remains a target, especially now that they are far behind their rivals. Barcelona is bad in La Liga, not because they focus on the UCL league, they are indeed slumping both in La Liga and in the UCL League. Even though they managed to qualify for the round of 16, for me this was a bad performance for Barcelona because usually in the group phase they always wipe out full points but this time they failed to achieve success, even though in group H it could be considered that Barcelona had an easy opponent, but they lost twice.
Barcelona's skills are not doubted by most people, but everyone has also seen the true reality this season where Barcelona is starting to fall behind and there is a possibility that it will be difficult to win in the Champions League even though Barcelona wants to make the Champions League their priority this season very well.
It seems that Barcelona is below its current level so it is not surprising that they are inconsistent, especially since they have problems with the club's finances, of course it is difficult to bring in players. The current Barcelona team still needs a longer process to return to top performance so they can compete again at the highest European level.
