Arsenal manager Arsene Wenger however has remained calm on the matter.
“When you go from Fenerbahce to Dortmund, you are used to these kind of atmospheres and we know how to deal with that,” said Wenger, whose side will advance if they avoid a three-goal defeat in Napoli.
Arsenal has had a smashing season so far atop of their group in the Champions League and atop the table of the English Premier League.
"When we manage to play our game, it is always very difficult for the opponents because they have to defend deep and be compact," said star-striker Olivier Giroud, a crucial part of Arsenal's recent success.
Also in Group D Wednesday, last year's CL finalist Borussia Dortmund will play win less Marseille. Dortmund and Napoli are both equal on points with nine but Dortmund has a much better goal differential.
