Borussia Dortmund Jurgen Klopp says he does not expect 'Champagne football' from his side as they battle to avoid relegation at the bottom of the Bundesliga.

Dortmund slipped back into last place despite Saturday's goalless draw at fellow Champions League side Bayer Leverkusen.

Before kick-off, Freiburg's 4-1 comeback win at home to Eintracht Frankfurt had lifted Christian Streich's side up to 13th had sent Klopp's side bottom for the first time since November.

Despite their precarious position, Dortmund are just three points from mid-table ahead of Wednesday's Bundesliga match at Augsburg.

"That was an important point. I am happy, we're within in striking distance," said Klopp as Dortmund endure their worst start to a Bundesliga season for 30 years.

"That was a tough game to start the second half of the season and was very intensive football.

"I can't preach that we are in a relegation battle and demand Champagne football."

Borussia failed to break the hosts' defence at Leverkusen's BayArena as Borussia's Italy striker Ciro Immobile squandered several second-half chances.

At the other end, Borussia's Germany defender Mats Hummels headed Gonzalo Castro's first-half shot off the line in the hosts' best chance after Castro had earlier shot over the bar.

"We can live with that. This isn't an easy place to come and pick up anything," said Dortmund's new signing Kevin Kampl.

"We knew they had an extremely good pressing game, perhaps it wasn't the best football, but the main thing for us is to pick up points -- even if it was just one today."

With just 16 points from 18 games, Klopp has serious problems up front as his attack has netted just 18 goals all season.

Klopp's new strikers Immobile and Adrian Ramos have struggled to provide the 22 goals Robert Lewandowski hit in 34 games last season before joining Bayern Munich.
