The Brazilian wants Barca to redeem themselves in Europe this season after their ignominious 7-0 aggregate defeat to die Roten in this year's Champions League semi-final
The Blaugrana were beaten 7-0 on aggregate by the Bavarians, who went on to vanquish Borussia Dortmund 2-1 in the final.
However, the Brazil international is confident that the heavy loss and the failure to reach the Wembley showdown is enough to make sure that the club redeem themselves in their European campaign this season.
"There was no excuse for what happened," the 30-year-old told Mundo Deportivo, "and we really want to show this season that it was an accident.
"No-one can lose a semi-final 7-0 – it is outrageous for a team of our level. We were deservedly knocked out but the good thing about football is that sometimes you get a second chance."
Alves also backed his former trainer Tito Vilanova's decision to depart from football because of health issues and talked positively about Gerardo Martino's newly introduced tactical concepts.
"Tito was a good assistant and coach for five years. As an assistant he had an important role," he continued, "but I think he has made the right decision – life is always more important than your career.
"There are some new concepts [under Martino] but I can assure you that they are working. We are coming up with new strategies and becoming stronger as a team."
