Guerreiro, whose contract at the German club is up in 2020, chose not to accept their contract renewal offer, leaving Dortmund with no choice but to sell the Portuguese international this summer.
'TMW' reported that Guerreiro has now been added to the transfer list, with Dortmund conscious of the fact that this is their last chance to cash in on the 25 year-old, who has played 32 games and scored 6 goals this season, before he can leave for free next summer.
PSG are one team who have showed an interest in him, with a possible reunion with ex-Dortmund coach Thomas Tuchel on the cards in the French capital.
