Allan is prepared to leave Napoli this summer.
The Brazilian midfielder is a target for Everton and PSG - and TMW says he's now prepared to leave.
Napoli president Aurelio de Laurentiis had been quoted a price of €70m to sell Allan earlier this year.
However, he is now prepared to accept €40m for the midfielder given the transfer market correction due to the coronavirus suspension.
Everton are regarded as favourites for Allan, with manager Carlo Ancelotti having worked with the midfielder at Napoli.
