Arsene Wenger has pinpointed the threat of Napoli's Lorenzo Insigne ahead of Arsenal's Champions League clash with the Serie A giants, a player he recognises as one with "interesting potential".

Napoli travel to the Emirates Stadium in imperious form, second in Serie A having amassed 16 points from their opening six games as Rafa Benitez aims to wrestle the Serie A crown off Juventus in his first season back in Italy.

The club got their European campaign off to a winning start with a 2-1 win over last year's runners up Borussia Dortmund, a victory marked by a spectacular free kick from Insigne. The 22-year-old has already shown the Gunners what he is capable when he got his name on the score sheet in the 2-2 draw between the two clubs in the Emirates Cup during pre-season, and Wenger is wary of the threat the diminutive forward will pose.

"He (Insigne) is mobile, he is not tall but quick and very good in the transition from defence to attack," Wenger told Arsenal's official website.

"He is a good dribbler as well and is an intelligent mover. That makes him an interesting prospect.

"That is what struck me as well in the Emirates Cup - when they with the ball they come out very quickly with Callejon, Hamsik, Insigne and Higuain, who come out like bombs all the time they win the ball. The transition from our side from offence to defence will have to be very quick."

Arsenal got their own Champions League campaign off to a bright start by picking up three points away to Marseille, a critical win for the Gunners with daunting trips to Dortmund and Napoli on the horizon.

But with consecutive home games to come first, Wenger is fully aware a win will hold the club in great stead for qualification to the knock out stages.

"They had as a surprising result for many people because Dortmund reached the final last year in a very emphatic way," the Arsenal boss continued.

"To beat them certainly is something special and that will lift their confidence. We know from the Emirates Cup that they are a good side but we know as well when you want to qualify then home games are vital.

"We have started very well but you know if you win the second game at home you have a good chance to qualify. But I wouldn't say it's already a decisive game.

"It's a game that will have a great weight on the end result of the qualifying teams. Let's deal well with that situation then we will be in a positive mood to finish the job."
