Newly-elected Barcelona president Josep Maria Bartomeu believes that the Catalan outfit will be 'even more competitive' this season.
Bartomeu has admitted that the 2014-15 campaign, which brought a treble, was "probably the best season" in the club's history.
However, the Spaniard believes that the signings of Arda Turan and Aleix Vidal will mean further improvements in the new campaign.
"Last year was probably the best season in our history because we won everything. This year we have tried to work with the same team but also bring in some players who can give us a bit more competition for places, like Arda Turan and Aleix Vidal," he told BBC Sport.
"In our opinion, our team will be more competitive. This year we have six possible trophies – La Liga, Copa del Rey, Champions League, Spanish Super Cup, European Super Cup, World Club Cup – that we want to win. It's not going to be easy but we are going to try."
Barcelona are currently on their pre-season tour of the United States.
