Ronaldinho has returned to Barcelona after being appointed as an ambassador by the Spanish club.
The former Brazil forward made over 200 appearances for Barca in five trophy-laden seasons at the Nou Camp.
During his stint with the Catalan giants, between 2003 and 2008, Ronaldinho won two league titles, two Spanish Super Cups and the Champions League.
The 36-year-old, who left to join AC Milan before finishing his career in his homeland, now returns to Barca in a new guise.
A statement on the club's website read: "FC Barcelona and Ronaldinho have reached an agreement whereby the Brazilian will become a club ambassador and representative at various events and activities over the coming years."
Ronaldinho, a World Cup winner in 2002, will be officially unveiled alongside Barca president Josep Maria Bartomeu on Friday.
