Having lost six out of nine games of the Bundesliga, BVB are looking for some respite in the DFB-Pokal, although their coach hinted his players are running on fumes
Jurgen Klopp has acknowledged that Borussia Dortmund are in a "critical" situation ahead of Tuesday's DFB-Pokal clash with St. Pauli.
The Signal Iduna Park side have lost their last four matches in the Bundesliga - leaving them hovering above the relegation places - but are overwhelming favourites to reach the third round of the German cup competition.
Klopp's position at BVB is under scrutiny and he conceded that his players might be letting their nerves affect performances, contributing to their shockingly poor results in the Bundesliga.
"The fear of not winning is certainly there," the coach told reporters on Monday. "Sometimes we lack the necessary rest to perform.
"But we have to work. The preparation has been normal despite the critical situation that we've found ourselves in.
"We know the nature of this competition, that we're out if we lose.
"A couple of the players are over-worked, but there are no new injuries."
Dortmund's cup clash at second-division side St. Pauli kicks off at 20:30CET on Tuesday.
Next up in the Bundesliga for last season's runners up is a daunting visit to champions and league leaders Bayern Munich.
