Borussia Dortmund coach Jurgen Klopp has admitted that his side are in for a tough game on Friday night in their Bundesliga clash against Stuttgart.

Klopp said that his team's good record against Der VfB is irrelevant as there has been a lot of movement in terms of players and behind the scenes at the club.

"You cannot compare them," he told Bundesliga.com. "Stuttgart's team is no longer the same anyway. They've got a lot of quality and are in good form."

Dortmund would move temporarily up to first in the table with victory.
