Jurgen Klopp's side target a new striker due to the possible departure of Swiss frontman Alexander Frei, the German daily added.

Ivorian international Sanogo, who joined Bremen from Hamburg in the summer of 2007, spent the second half of last season on loan at Hoffenheim.

He could play alongside Egypt forward Zidan in Dortmund's frontline next season.

Dortmund, who finished sixth in the Bundesliga last season, have already signed another striker in Energie Cottbus' Dimitar Rangelov.
