Barcelona president Josep Maria Bartomeu is putting Arda Turan up for sale.
AS says Bartomeu has informed Turan's agent, Ahmed Bulut, that Barca are now inviting offers for the Turkey international.
Inter Milan chief Piero Ausilio has been in touch, as has Arsenal.
Barca will sell to the highest bidder, seeking €40 million for the midfielder.
A loan to a LaLiga rival is also under consideration - for a fee of €7 million.
