Arsenal have been fined £34,000 and warned about their conduct during player transfers over the departures of Chuba Akpom and Joel Campbell in 2018.
A FIFA investigation launched in January found that the Gunners inserted clauses that demanded more of a cut of future transfer fees if either of their former players later joined a British club.
Greek club PAOK would receive only 40 percent of the fee if Akpom was sold to a British club but 30 percent if the striker joined any other team, according to legal documents seen by The Associated Press.
