Agree with this, because regardless of anything for now talking about them with the Champions League is clearly not very useful because they have been eliminated long ago and this possibility will probably be discussed again later after this season is over.
Regarding La Liga, they are actually very comfortable and are just waiting to see whether Leg 2 in the Copa del Rey will meet their expectations or not.
Barcelona really want to win the Copa Del Rey title this season, they are very serious about their hopes of getting to the final. Indeed, it is difficult to expect all the titles according to expectations, especially when Real Madrid is the opponent.
The good fact is that Barcelona have proven difficult things to be easy this season. Beating Real Madrid is always difficult, but they have done it 3 times this season which is a fantastic record. I can expect a draw in the second leg of the Copa Del Rey, that's still better than losing and failing to make it to the final.
