Arsenal defender Laurent Koscielny is of the view that the Gunners have the personnel and mentality to stop Luis Suarez, Neymar and Lionel Messi when the best attack in world football come to the Emirates for the first leg of the round of 16 tie of the Champions League. The Gunners last made the quarter-finals in the 2009/10 season and since then have fallen twice to Barcelona, twice to Bayern Munich and once each against AC Milan and Monaco.

The Gunners scraped past the group stage on goal difference, beating Olympiacos by three goals in the last group game to get into the knockout stages, but face arguably their biggest test thus far in the form of the defending Champions. Koscielny, who was in the heart of defence that beat Bayern Munich 2-0 at the Emirates, is confident that the game can be won if the Gunners hold their shape and defend deep like they did at the Emirates against Bayern.

The north London club know the importance of a good result at home, something that has eluded them off late. Their last three campaigns saw them concede crucial goals at the Emirates and despite their earnest attempts to get back into the game away from home, they were always found short against quality opposition.

"Just by looking at their statistics you see that they have the best offensive armada in Europe or even the world," he told French TV show Telefoot. "You just have to enjoy yourself and give 100 per cent to get a good result."

Koscielny has a plan to get the job done and expects Petr Cech to have a great game to keep the visitors out of his net. The Czech Republic international has met Barcelona six times with Chelsea and is yet to concede a single goal, including a two-way thriller in the semi-finals of the 2011/12 season when the Blues went on to lift the trophy.

"Yes it's possible," Koscielny said when asked if he believes that Arsenal have a chance. "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," he added.
