The only goalless draw of the night occurred at Signal Iduna Park where Dortmund and AC Milan played out a stalemate.
Both clubs are still searching for a victory in Group F, but it'll be Milan the happier of the two sides as the result leaves them just a point behind second-placed PSG, while Dortmund are bottom.
Dortmund lost 2-0 in Paris in the opening week, while Milan were held in a stalemate by Newcastle.
