Mesut Özil hit his first Arsenal goal as the Gunners maintained their 100% record in the Champions League with an easy win over Rafael Benítez's Napoli.

Özil's classy opener was followed by Olivier Giroud's close-range finish in the first 15 minutes, as Napoli struggled to contain their hosts' swift possession play.

Elsewhere in Group F, last year's runners-up Borussia Dortmund won their first game after defeat to Napoli two weeks ago. Robert Lewandowski scored twice and Marco Reus struck in their 3-0 conquest of whipping boys Marseille.

Chelsea ran out 4-0 winners in Bucharest, as Ramires scored twice, Frank Lampard got on the scoresheet and Daniel Georgievski put through his own net in the rout. Schalke won at Basel, which leaves them top in Group E.
