Barcelona manager Luis Enrique described his side's 6-2 thrashing of Real Betis as the "complete game".
Luis Suarez scored a hat-trick and Lionel Messi netted a double after Arda Turan put the La Liga champions ahead at the Nou Camp on Saturday.
Ruben Castro equalised for the visitors and scored a late consolation but the strikes failed to take the gloss off the Catalans' first match of their title defence.
Manager Enrique, who was without seven first-team players including Andres Iniesta, Javier Mascherano and Neymar, said it was the perfect start to his side's campaign.
"The players were very motivated, and very active both in attack and defence. We were brave and very effective. A complete game," he told the club's website.
While Suarez and Messi stole the headlines there were positive performances across the pitch in particular from full-back Sergi Roberto who played a role in two first-half goals and was a constant thorn in Betis' side.
"Sergi Roberto, down the same flank as always, very attentive in the defensive aspect of his game, and showed good anticipation. In attack, he was very good, looking for space and creating chances," Enrique added before praising his goalscorers.
"Arda has a lot of quality and can perform in the two positions, both as an inside midfielder and as a forward. And, on top of that, he scores goals. He is more integrated and happy.
"Messi was at an extraordinary level, as always. Luis Suarez also, both in attack and defence."
Following the match it was announced Claudio Bravo was nearing his anticipated move to Manchester City and Enrique said there could be new players yet at the Nou Camp.
"Any player that can improve the squad, which is not easy, the club will be open to the possibility of bringing him in."
