The Westphalians travel to rock-bottom Stuttgart for a relegation battle with just four points separating the two sides.
Despite Dortmund winning back-to-back matches to climb off the foot of the standings, Klopp said: “We’re still under considerable pressure.
“All that matters to us is staying in the Bundesliga. I’m not thinking about anything else.
“We will be fielding our full orchestra in Stuttgart. If we ever rotate, then it is only due to the strain and not dependent on the competition we are in.”
Changes may nevertheless be made to Klopp’s starting XI compared to the one which defeated Mainz 4-2 last Friday.
“We’ve got a flu virus doing the rounds,” he revealed at a press conference. “Erik Durm’s been ill for two weeks now and (Ciro) Immobile’s also been ill.
“Mats Hummels woke up not feeling well last Friday and he’s not turned up for training since, and I can’t see anybody coming back soon.”
Dortmund’s problems seem minimal in comparison to the struggles Stuttgart are currently enduring, however.
Without a win yet in 2015, Huub Stevens’ men have slumped to the foot of the table, while the Mercedes-Benz Arena has been anything but a welcome home for them this term.
The Swabians have lost seven times in front of their own fans this season, winning only once.
“Of course the situation’s not nice, but I’m nevertheless being positive about it,” said full-back Adam Hlousek on the club’s website.
“We can’t let it depress us too much because being pessimistic gets you nowhere.
“I always try to end my days with positive thoughts, and I am totally convinced that we will reach our goal at the end of the season.”
Sercan Sararer and Konstantin Rausch look set to play no further part in Stuttgart’s relegation battle having been dropped by Stevens to the reserve team.
