Arsenal beat Napoli

Mesut Ozil and Olivier Giroud netted in the first fifteen minutes, as Arsenal beat Napoli 2-0 in the Champions League Group F clash at the Emirates.

On Arsene Wenger's 17th anniversary as Gunners' manager, his team made it two wins from two games in the group and ensured a first win in Europe for their boss over Rafa Benitez at the fifth attempt.

Ozil scored the opening goal after seven minutes for Arsenal with a brilliant finish to convert Aaron Ramsay's cross from the right.

Arsenal were 2-0 up eight minutes later, with Ozil the provider this time with a run down the left and cross for Olivier Giroud to tap home.
  Benitez's side really struggled with the fluid movement of the Gunners, with Giandomenico Mesto, Miguel Britos and Camilo Zuniga in particular troubled by the runs of Ramsay and Ozil.

100 percent Arsenal face Borussia Dortmund in back-to-back games next in the group, with the first match on October 22 at the Emirates.

Borussia Dortmund beat Marseille 3-0 to go third behind the Gunners and Napoli.
Robert Lewandowski netted twice, with Marco Reus scoring the other with a free-kick.
Cesc Fabregas' late goal gave Barcelona a 1-0 Champions League Group H win over 10-man Celtic at Celtic Park.

Celtic captain Scott Brown was sent off just before the hour mark for kicking out at Neymar, and Fabregas took advantage of the extra man 14 minutes from time with a header from an Alexis Sanchez cross.
In the group's other game, Ajax drew 1-1 with AC Milan in Amsterdam.
