Arsenal defender Laurent Koscielny believes his side have what it takes to keep Barcelona's attacking "armada" quiet in the Champions League.
The Gunners host the reigning European champions in the first leg of their round-of-16 tie on Tuesday and will be hoping for a repeat of their success against the Catalans five years ago this month.
Robin van Persie and Andrey Arshavin scored in a 2-1 win the last time Barcelona visited the Emirates, although the La Liga leaders still went through after a 3-1 victory in the second leg.
Barcelona also beat Arsenal in the knockout phase in 2010 and in the 2006 Champions League final.
Having been frustrated in a 0-0 draw with Hull in the FA Cup, however, Koscielny, 30, is relishing the challenge of trying to quell the threat of Lionel Messi, Luis Suarez and Neymar.
"Just by looking at their statistics you see that they have the best offensive armada in Europe or even the world," Koscielny told French TV show Telefoot. "You just have to enjoy yourself and give 100 percent to get a good result."
Arsenal have suffered damaging first-leg defeats in the last 16 in each of the past three seasons -- twice against Bayern Munich and once against Monaco -- and manager Arsene Wenger warned that they "can't be stupid" in their approach against Barcelona.
But Koscielny feels that the Gunners have the potential to produce the type of disciplined performance that could give them a lead to protect when they travel to Spain for the second leg on March 16.
"Yes it's possible," Koscielny said, when asked about Arsenal's chances of winning on Tuesday.
"We have a great goalkeeper and beyond that when you talk about defence it's not only the back four. The whole team have to make the link between each line.
"If we're capable -- and we've already done it in certain Premier League matches -- to play deep, to know how to defend together and afterwards to counter them, we have a chance of getting a good result against Barca."
