Barcelona have confirmed Paulinho is leaving the club to rejoin Chinese club Guangzhou Evergrande on an initial one-season loan deal.
Paulinho scored nine goals in 49 appearances after joining Barcelona from Guangzhou Evergrande last summer in a €40m (£35.3m) move.
The deal taking him back to Guangzhou contains an option for the Chinese Super League side to purchase the midfielder outright.
Paulinho rose to prominence in his homeland for Sao Paulo-based Corinthians before he moved to Tottenham in 2013.
