In fact, there is a big difference between Barcelona in the Champions League and La Liga. I think one of the reasons is that La Liga teams are relatively far behind Barcelona. Barcelona are beating them fearlessly. But Barca could not be ready for the Champions League yet. The upcoming match against Real Madrid will show how successful Barca is in La Liga.
The debate on Barcelona's performance in the Spanish League is not in this topic. But I think that as things are, if they lose against Real Madrid, and they don't manage to continue in the Champions League (very likely), they will have a very similar season to the previous one.
If they finally get to win Real Madrid it'll mean a lot to Barca
Cause they have finally realized that they can't qualify to the next round in the Champions League
Playing Europa league has never been the option from the very beginning how painful it is to see Lewandoski in the Europa League Competition
I think Barcelona have played very well but they are far behind. We know Barcelona play very well but they haven't done anything good. So I think Barcelona can't go far. We have seen Barcelona play very badly in some matches.
