Brazilian full back returns to FC Barcelona after previously playing for the team from 2008/09 to 2015/16.
C Barcelona and Dani Alves have reached an agreement in principle for the player to join the football first team for the remainder of the current season.
The Brazilian will be joining training from next week but will not be able to play until January.
The club will announce the full details at his official presentation as a new FC Barcelona player.
Dani Alves came to Barça in the summer of 2008 after five brilliant seasons in Sevilla. In the Catalan capital, he made the right back slot his own across eight seasons, making 391 official appearances and scoring 23 goals.
Although his main role has always been in defence, in the true Brazilian wing-back tradition, Alves also likes to join the attack, where he has a fine shot from outside the area, earning him the reputation as one of the finest players of all time in his position.
He was an automatic choice under all of Pep Guardiola, Tito Vilanova, Tata Martino and Luis Enrique, and the fans loved his dedication and extroverted character.
In the summer of 2016, he left for Juventus, and since then has been at Paris Saint-Germain and lastly, at São Paulo back in his home country.
