Arsenal have been fined by FIFA over their player sales.
AP reports FIFA have fined the Premier League club £34,000 and the Gunners have been warned that they could face harsher sanctions in future.
It comes following an investigation into the transfers of Chuba Akpom and Joel Campbell in 2018.
Akpom was sold to Greek club PAOK, while Costa Rica forward Campbell joined Italian side Frosinone.
However, sell-on clauses placed in their contracts were variable, meaning if either returned to clubs in the UK, Arsenal would receive a bigger fee.
In Akpom's case, Arsenal would receive 40 per cent of the transfer fee if he moved to a British club, but only 30 per cent if he went elsewhere.
Frosinone would pay Arsenal 30 per cent of any fee if Campbell was sold back to the UK, but only 25 per cent if he went anywhere else.
The discovery of the sell-on clauses has seen an investigation take place since January, having not been initially declared.
