Alves moved to Barcelona in a €35.5m deal from Sevilla back in 2008, and he would go on to enjoy a glittering eight-year stint with the Catalan giants.
Dani Alves, who won three Champions League titles at the Camp Nou, revealed to his 31.7million Instagram followers that he did not believe in the Barcelona board, who were not open about their decision to sell him.
"I didn't believe in the board who were at the club at that time and later, my instincts were proved right," Dani Alves said via AS.
"As I was the first to speak out, people thought I was completely mad; actually I am a bit mad, but in a nice way."
Dani Alves moved back to hometown club São Paulo after spending two seasons in the French capital with Paris Saint-Germain.
The ex-Barcelona man was then asked who he believed boasts a better career between Lionel Messi and Cristiano Ronaldo.
"Despite the greatness of the two, a picture is worth a thousand words," Alves replied, revealing an Instagram image of him with Barcelona captain Lionel Messi.
