The future of Wolves winger Adama Traore is yet to be settled.
Currently on-loan with Barcelona, the Catalans have ruled out paying cash to sign the Spain international permanently.
Sport says Barca are open to extending the loan into next season or performing a swap. But they will not consider a cash deal.
Adama's agent, Jorge Mendes, is now working on the player's future.
Everton are keen, though any move is dependent on them avoiding relegation this season.
