Another major European club have approached the minders of Chelsea striker Olivier Giroud this week.
Off contract in June, Giroud is weighing up quitting Chelsea in January in frustration over his lack of playing opportunities so far this season.
Lyon, Marseille and Antonio Conte's Inter Milan are all in contact.
And BILD says Borussia Dortmund have now come forward, as they seek an experienced centre-forward signing for the winter market.
Also on BVB's shortlist are Juventus veteran Mario Mandzukic and departing LA Galaxy centre-forward Zlatan Ibrahimovic.
