Barcelona are reportedly open to offers for as many as 18 players this summer as part of cost-cutting measures.
The Catalan giants are in serious financial trouble as they look to bring a debt of around £862m under control.
Barca are focusing on free signings and have already brought in Eric Garcia and Sergio Aguero from Manchester City.
However, with a new deal for star man Lionel Messi also in the offing, the La Liga side are in desperate need of some incoming cash.
According to Goal, the seriousness of the situation means that Barca have accepted that a number of first-team players will have to move on in the next few months.
It is claimed that Gerard Pique, Sergio Busquets, Jordi Alba, Clement Lenglet, Antoine Griezmann, Philippe Coutinho, Miralem Pjanic and Samuel Umtiti are the highest-profile names that have been put up for sale.
Junior Firpo, Martin Braithwaite and Matheus Fernandes are also supposedly available to purchase.
In fact, Messi, Ronald Araujo, Ansu Fati, Pedri and Frenkie de Jong are the only players deemed untouchable by president Joan Laporta.
