Following back-to-back defeats, Borussia Dortmund coach Thomas Tuchel says his side must "get back to their true capabilities" as he looks ahead to Sunday's Bundesliga showdown with Stuttgart (28th November).

SOUNDBITE (German) Thomas Tuchel, Borussia Dortmund coach:

"After two defeats, this game (Sunday's showdown with Stuttgart) is an important one to turn this rough patch around. It is at home, so we need to be especially prepared, and show our true mentality again. And we have to keep faith in the things that we do well. We have to show hunger, aggresiveness and get back to our full capability."

(on last Friday's 3-1 defeat at Hamburg)

"The defeat (against Hamburg) really shocked me. Not just me, but the whole coaching team and the squad were also concerned. Even after the last defeat (at Krasnodor of Russia in the Europa league on Thursday), this defeat in Hamburg stands out because of the way we played and how far away from our potential we were. That was a first and at the moment we have to look at it that way."
