Ajax striker Sebastian Haller is on Borussia Dortmund's shortlist of strikers for this summer.
The Bundesliga giants are set to lose Erling Haaland to a European heavyweight, as the Norway forward has a release clause in his contract.
According to Bild, there are already preparations underway to replace Haaland this summer.
The source states that Haller, who has netted 33 goals in all competitions this term, could be BVB's primary target.
Sparta Prague's Adam Hlozek and Bayer Leverkusen's Patrick Schick are other possibilities.
