This is what is expected to be the new Dortmund home kit for 2019/20 as manufactured by Puma. The new BVB shirt is expected to be released in the next few days ahead of their final home league clash of the season against Fortuna Dusseldorf. (Sales will officially begin on 9-10 May, and the club have already begun taking pre-orders)
This pic looks like it might be the real deal. As always, EVONIK and Opel to be the shirt sponsors.
