Borussia Dortmund coach Jurgen Klopp believes that if his side fail to beat Arsenal on Wednesday, it will be their own fault.
The German giants recorded a 2-1 victory over the Gunners at the Emirates a fortnight ago thanks to Robert Lewandowski's late strike.
Klopp is looking forward to another tight match in the Signal Iduna Park return but called upon his men to deliver a great performance to stifle the north Londoners.
"It will be an intensive match with many duels," he said at a press conference. "At this level, neither team can surprise the other.
"Small things make a difference, such as when [Arsenal star Santi] Cazorla hit the bar [at the Emirates]. If Arsenal are stronger tomorrow that home it is because we let them be."
Arsenal are currently in the midst of an eight-month unbeaten run away from home but Klopp is focused on his own side making history.
He added: "Had we won the last 70 home games, it would be as much history as Arsenal's current away run. We want to write our own story."
Finally, Klopp hinted that Mats Hummels will not be involved on Wednesday, but said the outlook was more positive for left-back Marcel Schmelzer.
"At the moment, it seems that Mats will not play tomorrow. With Marcel it looks a lot better."
Finally, attacker Marco Reus echoed his coach's sentiments that Arsenal will pose a tough threat but is confident that BVB can emerge victorious.
"It will be another 50-50 match, I believe we showed a great performance in London and will have to do so again. We know the smallest mistake will be punished.
"We have improved since Napoli. You can't compare this to the league, this is the Champions League."
