Mats Hummels showed courage by agreeing to a return to Borussia Dortmund, according to sporting director Michael Zorc.
The World Cup winner is heading back to Signal Iduna Park, where he spent eight years between 2008 and 2016, in a reported €38 million (£33.8m/$42.5m) move from Bundesliga champions Bayern Munich.
Zorc is delighted to welcome Hummels back and believes the decision to depart the Bundesliga's dominant force after three seasons is a brave one.
