The 38-year-old, who made 391 appearances for Barcelona between 2008 and 2016, is currently available on a free transfer, having left Brazilian outfit Sao Paulo in September.
A recent report claimed that the Catalan giants had ruled out bringing the right-back back to the club amid suggestions that Xavi was keen on a reunion with his former teammate.
However, according to Sport, Xavi has now been given the green light to sign Alves, with the Brazilian's leadership qualities being viewed as vital in a young Barcelona squad.
Alves won six La Liga titles and three Champions League crowns during a hugely successful period at Barcelona, while he has lifted 43 trophies during his senior career. body check tags ::
