Arsenal goalkeeper Wojciech Szczesny says their victory over Champions League opponents Napoli earlier this season was the best they've played.
Arsenal are in Naples tonight.
"I think in the first half-hour [of the first Napoli game] we were frightening," Szczesny told Arsenal Player. "I never touched the ball so that should tell you a lot.
"But then again it will be a completely different game now, they play at home, they know they need to win, so they will probably throw everything at us and we're going to have to be focused to deal with that. But I believe we can turn up with the same sort of result again.
"I think it's important to finish top," he added. "This year as well most of the big boys are top of their groups so coming on top of our group will give us probably a better draw in the last 16.
"I don't think we should approach the game thinking that we need to avoid a defeat. We believe that we're good enough to go there and get a win. We don't need to change our attitude, we need to keep it going the way we have been and that should give us a result."
