Next week Real Madrid and Barcelona will face almost the same club. Real Madrid will visit Cadiz (14th in the table), while Barcelona will visit Getafe (15th in the table). Overall, statistically, this match shouldn't be a big problem for Real Madrid and Barcelona, but that's still not a guarantee, because even this week these two teams couldn't achieve maximum results. Now 10 weeks remaining in La Liga, and Barcelona surely they are only a few weeks away from claiming the title, provided they are consistent with wins.
Even though Barcelona's performance has been a bit down, I think they will be able to secure the La Liga title. Because Real Madrid is far behind. At the same time, the main goal of Madrid is the Champions League. And so I wouldn't be surprised if Madrid dropped points in a few more matches. Barcelona, on the other hand, is now completely pressure-free. Since they are 13 points ahead of Madrid, Barcelona won't face any major problems even if they lose 2/3 matches. Barcelona will win the title this time.
I don't think there is a possibility for Barcelona to somehow lose the title of La Liga even if they show bad performance in the games they are going to have still there is enough gap between them and Real Madrid mostly because of the recently match we saw from Real Madrid I can say they easily lost three points and after losing these three points they lost the lost hope for the La Liga title,
