A difference of 8 points is quite a wide gap and it will be quite a difficult mission for Barcelona to accomplish because La Liga only has 9 matches remaining. Even if Real Madrid slipped in some of their matches, there is still no certainty that Barcelona will not face the same obstacles because in terms of performance Barcelona is no better than Real Madrid. I think what is more possible for Barcelona is to let go of La Liga and completely focus on the Champions League.
Of course, that is quite a big difference in points because 8 winning points can only be achieved by winning 3 times and being superior, but Real Madrid must also not win in the existing match because if Real Madrid still easily wins then Barcelona will have difficulty catching up. , The La Liga competition also seems to be ending soon and I am not sure that Barcelona will take Real Madrid's position, Barcelona must accept its position in second place and must maintain it until it is finished and maybe it will be more active next season.
