Barcelona should continue with this form and they will surely lift the la Liga title and can still lift the champions League title this season, but Barcelona may lose a match in the la Liga as time goes on because I believe they are focusing more in the champions League that's why there performance is very good when they are playing any match in the champions League.
Real Madrid is the only team that can chase after them in the la Liga title race but since real Madrid is having a difficult time Barcelona has a lot of chance to win the la Liga title but if real Madrid gets disqualified in the champions League they will do everything within there power to make sure they lift the la Liga title.
Real Madrid and Barcelona are having divided attention over their LaLiga and Champions League matches, and both teams are more focused on their Champions League match than they have on the LaLiga match.
However, Real Madrid's next match in the Championship League against Arsenal will let us know how Real Madrid will be in their pursuit of the LaLiga trophy because it seems like they are not having that comeback against Arsenal. Real married will begin to take their LaLiga matches seriously because of that.
