The German magazine claims that the Egyptian will be moving to Signal Iduna in a part-exchange deal involving Dortmund hitman Mladen Petric.

The astonishing deal is coupled with the kickoff of the Bundesliga new season, which saw Hamburg holding champions Bayern Munich 2-2 on Friday.

After the game, HSV boss Martin Jol did not rule out the transfer, saying: "I do not know. We will talk tomorrow. Everything is possible."

Zidan was linked with Dortmund earlier this year, following the arrival of the 26-year-old's former Mainz boss Jurgen Klopp.
