The Germans host the Gunners at Signal Iduna Park in the fourth Champions League fixture of the campaign and Klopp is expecting another difficult even though his side saluted 2-1 in London last month.
"It will be an intensive match with many duels," he told reporters. "At this level, neither team can surprise the other.
"Small things make a difference, such as when [Santi] Cazorla hit the bar [at the Emirates]. If Arsenal are stronger at [our] home it is because we let them be."
"At the moment, it seems that Mats will not play," he said. "With Marcel, it looks a lot better."
