Reports have suggested the forward, who is currently on loan at AC Milan from Roma, is set to replace potential Dortmund target Heung-Min SonHamburg head coach Thorsten Fink has remained coy on reports linking current AC Milan forward Bojan to the Bundesliga club.
Sky Sport 24 suggested this month Heung-Min Son's possible exit could trigger a move for the Roma attacker, who is on loan at San Siro but still owned by Barcelona.
Goal reported that Son is Borussia Dortmund's top target should Robert Lewandowski jump Jurgen Klopp's ship at the end of the campaign, but Fink has called for transfer talk to resume once the 2012-13 year is complete.
"I have not thought about this player [Bojan]. First I would like to finish this season, then we can talk about players," the Hamburg coach told reporters on Tuesday. "[However], we need improvements in every part of the team."
The 22-year-old's future remains up in the air following a fairly anonymous year on loan at San Siro.
Fink's Hamburg side sit seventh in the German top division with two games to go, with a four-point gap to the fifth place needed to qualify for the Europa League next season.
