Ernesto Valverde made eight changes to his side at the break, giving the likes of Clement Lenglet and Arthur a chance to sample the Camp Nou atmosphere, but it was one of those who remained on the field who had the first chance of the second period.
The Argentinian has also admitted the Champions League disappointment outweighed the joy of winning the double.
"We have a squad to get excited about, those who have arrived will help us to improve a lot and if last year was very good with the Copa and La Liga, it's true we have remembered what happened to us in the Champions League with our elimination and this year we will do everything possible to bring this attractive cup back to Camp Nou".
Lionel Messi says following in the footsteps of Andres Iniesta, Xavi and Carles Puyol is an honour and being taught by the trio stands him in good stead as Barcelona's new captain, with the aim of bringing the Champions League trophy back to Camp Nou.
"We promise that this season we will do all we can to bring that trophy back to Camp Nou".
Messi said the club will "do everything possible" this season to prise the Champions League trophy away from arch-rivals Real Madrid.
Reflecting on his appearance alongside five-time Ballon d'Or victor Messi, Malcom said: "I have no words to define it".
Barcelona, who beat Sevilla 2-1 in the Spanish Super Cup on Sunday, begin the new La Liga campaign at home to Alaves on Saturday.
He added: "It's a source of great pride to be captain".
"I want the market to close so I know who I can count on".
"We're going to miss the great Andres a lot this year", said Messi.
