Luhukay said that Friday night's opponents Stuttgart would provide a tough test for his defence, but that if his side can remain disciplined they have the ability to take all three points.
"Stuttgart are organised, very good on the ball and have very quick attacking players who can hurt us," Bundesliga.com quotes Luhukay as saying.
"We have to be disciplined over 90 minutes and we want to get back to winning ways after the Wolfsburg game. That is our motivation for this game."
Hertha won two of their first three league games before losing to Wolfsburg before the international break.
