Dortmund head into the game at the TQL Stadium, Ohio knowing a point will be enough to qualify for the round of 16. This is regardless of the outcome between Fluminense and Mamelodi Sundowns.
Though, for Niko Kovac’s side to have any chance of topping Group F they’ll need to win and better the Brazilian outfit’s goal difference – if the two teams can’t be separated at the final standings.

Jobe Bellingham, fresh off opening his account for Dortmund, is expected to feature in midfield once again but there are question marks over Jamie Gittens’ involvement amid talk of a move to Chelsea.
