The 45-year-old trainer expects no drop in his team's commitment to winning a third consecutive Bundesliga title, despite their recent loss to bitter rivals Bayern Munich
The Borussians coach will be hoping for an improved performance from his team after the disappointment of losing 2-1 to Bayern Munich in the DFB Super Cup.
"The fans will be able to see that the team is playing with the same heart and the same passion for the cause," the 45-year-old told reporters 13 weeks after lifting their second consecutive Bundesliga title.
"We want to show that we can defend well in the early stages", he added.
Klopp's preparations for the season-opener may be hampered by the loss of a number of key players to injury, however.
Right-back Lukasz Piszczek failed to train on Wednesday with a thigh strain and may also miss tomorrow's session.
Meanwhile, star midfielder Mario Gotze is unlikely to feature from the start due to an eye infection, which also consigned him to a place on the bench against Bayern Munich.
