The Frenchman believes his team were always in charge against the Ligue 1 giants and is confident they can get the point they need against Napoli to progressArsene Wenger was pleased with the control Arsenal showed in their comfortable 2-0 Champions League win over Olympique de Marseille on Tuesday.
Goals from Jack Wilshere in the first and 65th minutes at the Emirates Stadium sealed the Gunners' convincing win, in which Mesut Ozil had a first-half penalty saved.
A point in Napoli in their last pool match will guarantee Arsenal of qualification to the round of 16 and Wenger feels this is well within the reach of his team.
"We were in control and it looked sometimes, yes, that we lacked a bit sharpness to finish the game off," the Frenchman told ITV.
"Overall we were always in control and our only regret is that we could have scored more goals.
"You have 12 points and five games. That's a good number of points. I'm confident we can take a point or three in Naples to go through.
"It's an interesting one of course, a difficult one. We have played other difficult games away from home against other opponents and did well. That's what we have to put in our mind."
