Right now, PSG’s focus is on their Champions League tie with Atalanta and no further talks will take place while they are still in the competition.
The Brazil under-23 international only joined Hertha in January, signing for a reported €18m from RB Leipzig.
With good financial backing, Hertha have no need to sell, but PSG’s project and presence of Neymar could tempt Cunha.
According to SPORT BILD, Hertha will accept no less than €50m for Cunha.
Cunha has found the net five times in 11 appearances since arriving at the Olympiastadion.
