The 31-year-old right back joined the Catalan giant from Sevilla in 2008 and has won a plethora of trophies at Camp Nou, including four La Liga titles as well as two Champions Leagues and Club World Cups.
But the Brazilian, who has been linked to a move to Paris Saint-Germain recently, said that he feels hurt by the amount of criticism he and the team have received this term as it crashed out of the Champions League and continues to trail Atletico Madrid in La Liga. As a result, he claimed he could leave the club this summer.
"It’s very hard to get the chance to play for Barcelona and, whether people like it or not, I’m part of the history of this club," he told RAC1. "I need energy, it’s what motivates me; I’m an upbeat, happy person.
"I’ve always been like that, but because the results aren’t what people expect, they need someone to shoot at and I feel shot at. I really believe in energy, I live off this energy and, if you start to create negative energy, things don’t flow.
"If this energy doesn’t change, I’ll probably leave because it wears you down. If I'm to stay this summer, there has to be a change of energy."
Alves then turned his attention to his side's title run-in. With two weeks of the season remaining, they sit three points behind league leaders Atletico Madrid, who they face on the final day.
