Overview
- Book, presented Wednesday after Sebastian Kehl’s exit a day earlier, signed a contract through 2029 to lead Borussia Dortmund’s rebuild.
- Dortmund frames the hire as a restart built on deeper scouting and player development, with Book vowing to “find pearls” that fit a clear team plan.
- A key planning hurdle has emerged as Bild reports Serhou Guirassy’s exit clause is about €35 million and only activates in July, which could slow early summer deals.
- With Julian Brandt set to leave after the season, reporting links BVB to Nikola Vlasic as a Niko Kovac–backed option and to 19‑year‑old prospect Ian Subiabre.
- Book joined after Elversberg agreed a clause that let him depart for Dortmund, and his long-standing bond with the club has drawn a warm fan response to his appointment.
