Arsenal goalkeeper Wojciech Szczesny warned “it will be a completely different game” against Napoli tomorrow.
The Gunners won 2-0 in London and can go through if they lose by less than three clear goals at the San Paolo.
“I think in the first half-hour we were frightening,” Szczesny told Arsenal.com of their October victory.
“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 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.
“It’s a Champions League fixture which is always enjoyable, you’re always up for it. I don’t think there will be any problems with our approach to the game.”
