Barcelona won the King's and League titles in the season, but the defeat of the Champions League means that this season has basically ended, the only task is to be able to complete the season with unbeaten record!
Barcelona already being the most unbeaten team in Laliga history and people wil remember this achievement but they still able to continue their record until end of this season and for upcoming games against Levante should not problem for them because Levante is weak teams
According to statistics Barcelona is known to sometimes struggle against Real Sociedas even though they havent beaten the Catalan side in their last five games and with that being the last game of the season, it would be in bad taste for Barcelona unbeaten season to come to an end at the Camp Nou in the last game of the season.
