The Brazilian's representative says his friendship with Real Madrid president Florentino Perez meant the pair were never close.
Neymar's agent Wagner Ribeiro has told Goal he has no relationship with former Barcelona president Sandro Rosell.
Ribeiro and Rosell worked together on the deal that saw the 23-year-old forward join the Catalans from Santos in 2013, though that transfer has since been the subject of a criminal investigation.
"My relationship with the former president at the moment does not exist," the agent stated to Goal. "He was not very cordial with me in the negotiations because he knew of my relationship with Florentino Perez of Real Madrid.
