FIFA have ruled that sell-on clauses placed in contracts were equal to third party ownership as Arsenal retained influence on future transfers.
The Gunners sold Chuba Akpom to PAOK and Joel Campbell to Frosinone in 2018, with sell-on clauses in both their new contracts.
Arsenal would receive 30 per cent of any future Akpom transfer from PAOK, unless it was to a British club when it would rise to 40 per cent.
The same clause was in Campbell’s contract, but it was 20 per cent rising to 30 per cent.
Campbell has not returned to these shores and currently plays for Leon in Mexico, but Akpom has moved back to Britain, signing for Middlesbrough in 2020 for £2.75m, of which Arsenal could claim 40 per cent.
The £33,000 fine is small change for the Premier League giants, but they clearly wish to see the decision overturned so as to protect future earnings and allow them to continue the practice of inserting such clauses.
