Arsenal secretary David Miles admits drawing Barcelona in the Champions League is the last thing fans would have wanted.
The Gunners have beaten the defending champions just once in seven meetings and even that was not enough to prevent an aggregate defeat in the knockout stages in 2011, their most recent encounter.
"On the back of the great win in Athens we were hoping for a good draw today and I think it's the tie of the round," Miles said.
"It's not going to be easy and it's the team that most Arsenal fans would have wanted to avoid at this stage but it's up to us to make a good fist of it.
"We've got our own world-class players and certainly we'll go in for this.
"It should be two fantastic games and we're very much looking forward to it."
Barcelona director Albert Soler is looking forward to a feast of football over the two legs.
"Football fans will enjoy themselves, we're two sides that play similar styles with a similar understanding of the game," he said.
"They will be two great games. We must have maximum respect for Arsenal, they're a great side and although we will have a difficult task facing us, it will be a guaranteed spectacle of football.
"Arsenal are not the favourites here but we do not consider ourselves outright favourites either. We are not taking anything for granted in this fixture."
