Neymar has reportedly considered making a formal complaint to FIFA against his former club Barcelona over an unpaid loyalty bonus.
The Brazil international completed a world-record move to Paris Saint-Germain on Thursday after the Catalans received full payment of his €222m (£200m) buyout clause.
Barca went on to issue a statement confirming that they would not pay a £23m bonus to Neymar's father following a contract renewal last year, due to the player not having met three specific conditions regarding his move away from Camp Nou.
According to Sky Sports News, the most expensive signing in world football feels "very bad" over the withheld payment, quoting a source in Spain close to the player.
The report goes on to claim that Neymar's lawyers have yet to lodge paperwork to world football's governing body but the option remains under consideration.
Neymar's father has been handling his son's transfer affairs for the entirety of his playing career.
