Borussia Dortmund interested in signing Hakim Ziyech and Denis Zakaria

However, transfers of this magnitude are only possible with matches. Roman Bürki is expected to leave the Bundesliga club after falling behind Gregor Kobel and Marwin Hitz, while the BVB may also terminate Reinier's loan six months ahead of schedule.

With these two players out of pay, Borussia Dortmund are considering a loan with a buy option from Ziyech, while Zakaria is available on a free transfer in the summer, but for around €8m it may be possible to sign the Swiss midfielder in January .
