The Brazilian midfielder was a surprise addition at Camp Nou in 2017 and is not ruling out a second stint
Paulinho is leaving the door open for a second move to Barcelona, with the Brazilian midfielder another free agent option for the Liga giants to consider this summer.
Sergio Aguero, Eric Garcia and Memphis Depay have already been snapped up at the end of their contracts at Manchester City and Lyon, with Ronald Koeman bringing in reinforcements that have required no transfer fee.
Paulinho may be another addition to explore, with the 32-year-old severing ties with Chinese side Guangzhou Evergrande, and he has already spent one season at Camp Nou after becoming a surprise signing in 2017.
