Morale the chief concern for Dortmund boss Klopp

Borussia Dortmund coach Jurgen Klopp says the biggest challenge he faces right now is keeping morale levels high.

A draw at Paderborn last weekend, which also saw Marco Reus pick up an injury which rules him out until January, has left Dortmund inside the bottom two of the Bundesliga.

In midweek, their perfect record in the Champions League was ended by Arsenal and Klopp admits spirits have seen better days.

"That's the biggest challenge in this situation," Klopp said at a press conference. "Ensuring we don't lose our positive outlook."

That applies as much to the fans as it does to his players.

"I do understand what it means to be dissatisfied, but I have a different way of dealing with it," he said.

"What I wouldn't find helpful, for example, would be if the fans were to start booing us.

"This is a chance for us all to prove that, even in a situation like this one, there is nothing which can come between us and our fans."

Frankfurt put some daylight between themselves and Dortmund with a 3-1 win away to Borussia Monchengladbach last weekend, but he wants his team to follow that up with a strong showing in front of their own fans.

Frankfurt have already lost three times at the Waldstadion this season and, as such, boss Thomas Schaaf believes they have lost a bit of their edge at home.

"I want it to be such that when teams arrive here, they feel they would be better off getting straight back on the bus and going home," Schaaf said on sport1.de.

"We can make that impression on Dortmund too, and it can make a difference.

"Dortmund have a great side with fantastic players. It's going to be tough, but very exciting at the same time."

Already deprived of Reus, Klopp will be hoping that Mats Hummels and Sven Bender will be fit enough to play with both currently carrying knocks.
