For this season, Barcelona will try to catch up even though it is very difficult because they are already far behind Real Madrid who are at the top of the standings, but with their quality which is now getting better I think they will try as hard as possible because mathematically they still have a chance to do that. .
And realistically Barcelona only has a bigger chance in the UCL so now they are also shifting their focus there to give their best performance, now Barcelona is in the quarter-finals so their journey is not long, even though it is difficult.
Indeed, mathematically Barcelona still has that chance, but if no team succeeds in stopping Real Madrid until the end of the season then everything will be in vain. Apart from that, Real Madrid doesn't just need one defeat but at least four defeats if Barcelona wants to overtake them at the top of the standings. With that, it would be very impossible for Barcelona, but I have little faith that sometimes miracles do happen.
Well, maybe it's true that the only title they can win this season is the Champions League, but they again encounter problems when other strong teams are in this round and things will be difficult for them again. If they manage to beat PSG in the next champions league they will face a much stronger team and with their readiness completely out of control at the moment, I doubt they can go any further.
