As well as those two, Barca are also ready to let Ousmane Dembele, Nelson Semedo and Samuel Umtiti walk away from the club.
Earlier this week, Barcelona president Josep Bartomeu admitted the club will probably look at player exchange deals in the coming window.
The La Liga giants are also linked with a big-money move for Lautaro Martinez, therefore they will need to offload players to fund both deals.
Bartomeu did, however, insist that Barca will continue buying top players this summer.
