Borussia Dortmund have moved quickly to strengthen their squad ahead of the 2021/22 Bundesliga campaign, with Marco Rose brought in as head coach as BVB go in search of a first Meisterschale since 2011/12.
That wait for a league title enters its 10th year this season, which is why Dortmund called upon the Borussia Mönchengladbach coach to bring fresh ideas to the table.
The 44-year-old former Mainz defender has been one of the league's standout coaches since arriving in Gladbach from Red Bull Salzburg in 2019 and he is handed over a side buoyed by their DFB Cup triumph that closed out 2020/21.
Caretaker boss Edin Terzic was the man that secured cup glory, while also leaving UEFA Champions League football for his successor to enjoy in his first term as the likes of Erling Haaland and Jadon Sancho powered Dortmund over the line at the end of the campaign.

That certainly strengthens the Dortmund defence, something 17-year-old Soumaila Coulibaly will hope to also do over the years to come after joining from French outfit Paris Saint-Germain.
The talismanic Poland defender Lukasz Piszczek won't be there to aid the cause, however, after leaving the club for Goczalkowice in his homeland.
Fellow long-serving full-back Marcel Schmelzer also departs after 13 years with Dortmund, while Leonardo Balerdi and Jeremy Toljan have made their respective loan moves at Marseille and Sassuolo permanent.
Sergio Gomez, Immanuel Pherai and Marius Wolf, meanwhile, all return to the club after loan spells of their own away from the Signal Iduna Park last year.
