Club A wishes to engage a player from Club B. Club B requires a transfer fee of EUR 20 million. Club A offers to pay Club B EUR 5 million and to agree on a sell-on clause corresponding to 60% of the fee received by Club A for a possible future transfer of the player. Is this option in line with the FIFA RSTP? Select one: a. No, because sell-on clauses are abusive and therefore prohibited by the FIFA RSTP. b. Yes. Sell-on clauses are not prohibited by the FIFA RSTP. c. Yes, but only if club A and club B use the same football agent. d. No. Because a third party would be entitled to receive compensation in relation to the future transfer of the player
