Neymar is considering a formal complaint to FIFA against his former club Barcelona over an unpaid loyalty bonus, according to Sky Sports.
Sky Sports News understands that the most expensive signing in world football feels “very bad” over the withheld payment, according to a source in Spain close to the player.
Barcelona are refusing to pay a £23mbonus to Neymar's father following a contract renewal last year.
It is understood Neymar's lawyers have yet to lodge paperwork to world football's governing body but the option remains under consideration.
