I think Barcelona have a great chance to secure the La Liga title. But if Barcelona meet Real Madrid in the knockout stage, I will be a bit worried. Because most of the time Barcelona team fails to fight against Real Madrid.
In what knockout stage? There is no knockout stage in the La Liga and Real Madrid and Barcelona can no longer play each other this season. If Barcelona beat Espanyol on the 14th of May, they would secure the La Liga title with 4 games remaining to play. So many people may say Xavi and Barca didn't have a good season because they were eliminated from the champions league in the group stage, and were also eliminated from the Europa league and copa dey rey, but i think Xavi and Barca did well, to take the title from this Real madrid team is not an easy thing to do. Next season they will be playing as La Liga champions, so it should help them to also do better in other competitions.
