Despite that setback in their Group F campaign, Ramsey insists that Arsenal are full of confidence heading into the tie.
"The atmosphere in their stadium is tremendous but you want to be playing in these sorts of atmospheres," the midfielder told the club's official website. "Everyone in the team will be looking forward to it.
"We don't go anywhere with fear - we will approach it the same as any other game. It is a massive week and one that we are looking forward to."
Arsenal go into the match ahead of Dortmund and Napoli on goal difference at the top of Group F.
