Barcelona are eyeing Juventus midfielder Dejan Kulusevski.
TMW says Barca are open to setting up a swap deal for the Sweden international.
The Catalans want to offer Dembele to the Bianconeri in a swap deal for Kulusevski.
Both clubs swapped Miralem Pjanic for Arthur in the last summer transfer window and Barca wants a similar deal for the second summer running.
Dembele's contract runs to the end of this season.
