Barcelona have denied paying part of the €222 million (£198m/$259m) they received for Neymar to executive Andre Cury.
Spanish radio station Cadena SER claimed on Thursday that Cury, an advisor to the Catalan club in the South American market, was given €6.6m as part of Neymar's move to Paris Saint-Germain last year.
Cury has rejected the report, according to Catalan daily Sport, and the club have since issued a statement insisting he received no such payment.
