Everton and Arsenal are on red alert as PSG prepare to make a raft of players available this summer.
PSG need to raise at least €100m by the end of June to balance the books and meet UEFA Financial Fair Play requirements.
Kevin Trapp, Grzegorz Krychowiak, Giovanni Lo Celso and Jese are all expected to go, having spent part of this season away on-loan.
Slso set to be sold is long-term Everton target Thomas Meunier plus midfielder Christopher Nkunku.
Arsenal attempted to sign Nkunku in January but ran out of time to settle terms. They're expected to try again this summer.
