As they have already won the Spanish Super Cup this term, yet another triumph would mark a successful campaign.The Blaugrana will return to action on May 2 to take on Osasuna in a La Liga home clash. Osasuna have been in good form and have reached the final of the Copa del Rey this season.Barca currently have 79 points from 32 games and lead second-placed Real Madrid by 11 points. Hence a win against eighth-placed Osasuna would be massive for the team as they look to become Spanish champions.
