Dani Alves left Barcelona after his short-term contract was not renewed last month.
In an interview with The Guardian, the Brazilian said Barcelona “do not care about the people who made history for the club” following his release.
Alves admitted his disappointment in the manner of his exit.
“I didn’t leave sad. I left happy to have returned to Barcelona. I dreamed for five years of wanting to experience this second moment.
“The only thing I didn’t like was how my departure was handled.
“Since I arrived, I made it very clear that I wasn’t a 20-year-old guy anymore and that I wanted things to be done head-on, without hiding things.
“But this club has sinned in recent years. Barcelona don’t care about the people who made history for the club.
“As a [Barca fan], I would like Barcelona to do things differently. I’m not talking about myself because my situation was another scenario.
“I am eternally grateful to Xavi and the president for bringing me back. I found a club full of young people with incredible ideas on the pitch.
“But it needs to improve the work off the field. The mindset is totally opposite to what we built a few years ago.
“Everything that happens on the field is a reflection of what happens off it.
“I’m supporting Barcelona to come back to the top, but it’s super-complicated. Football is more balanced, it’s a collective game. And that has been left out at the club.”
