Borussia Dortmund coach Thomas Tuchel says he is not sure how many fit players he has available for the Bundesliga encounter against Hertha BSC on Friday evening.
The Signal Park-based outfit host the second-placed team in the league, with Tuchel conceding that a lengthy list of absentees has left him struggling to assemble a full squad for the fixture.
"We're not sure whether we have 16 players available," he told the club's official website. "We're hoping for the crowd's support."
Dortmund have turned their home ground into a fortress, with The Black and Yellows currently enjoying a 24-match unbeaten run on home soil, which dates back to April, 2015.
Tuchel highlighted the need for his team to be compact at the back against a side that has netted 11 times in six games in the Bundesliga.
"I expect Hertha to be compact and to show great tactical discipline," he continued.
"It is incredibly difficult to create chances against this team. We'll need to play at a high tempo and show persistence if we want to get a result.
"When you're playing the patience game, you need to avoid getting hit on the counter. Indeed, it would not be unlike Hertha to do just that," he concluded.
