Having won their opener over Al Wasl 2-0, the Black and Yellows continued their 100 per cent record on Sunday night.
Dortmund now face a top-of-the-table clash with Al Wasl on Tuesday, with both teams’ progress already assured through to the semi-final stage of the competition.
The prize for winning that tussle would be pole position in Group A and the chance to play the second-placed team in Group B.
