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.
If Barcelona wants to take over Real Madrid's position then they have to wipe out the remaining matches they have with a win and Real Madrid have to lose at least 3 matches, then Barcelona will be at the top of the standings. However, the problem is that REal Madrid will not just let their position be taken away, especially since they will still meet in the El Clasico match. If Real Madrid wins that match then Barcelona will be further away from Real Madrid, but if Barcelona wins then it will slightly open up their chances of catching Real Madrid.
I don't think Barcelona can take over real madrid positions anymore, because real madrid can't lose three matches straight to make Barcelona top them in the league table, if Real Madrid loses match now he will be against el clasico madrid will win or lose the match, because it's been a long time when Barcelona and Real Madrid meet and draw definitely one person most win the game, and I give Barcelona hope because last season madrid defeated barca in the camp no Since Xavi is regaining form, I believe he will not give Ancelotti much chance against him this time around. And Madrid will not too put effort on the match because they have serious match in the UCL against Manchester City, they won't try to risk there key players in the league anymore.
