Barcelona are so close to making their league title official now. Espanyol is their next opponent and winning against them will guarantee their championship this season. Espanyol might cause some trouble maybe because of trying to get out of the relegation zone. But I don't think it would be a big deal for Barcelona as long as they play their usual game for the declaration of their championship.
The only fun thing to watch in the La Liga is the competition between Real Madrid and Atletico Madrid for the 2nd position now. Real Madrid don't seem to be very dedicated about it though.
