Arsenal striker Olivier Giroud struck twice as France stayed top of World Cup qualifying Group A with an efficient 3-1 victory in Luxembourg on Saturday.

Giroud, who has only started seven Premier League games for Arsenal this season, found the back of the net in each half and Antoine Griezmann scored a penalty after Aurelien Joachim had equalised for the hosts.

Didier Deschamps's side, who looked shaky in defence, now have 13 points from five games, three ahead of Sweden who beat Belarus 4-0.

France take on Spain in a friendly at the Stade de France on Tuesday before resuming their World Cup qualifying campaign with a trip to Sweden on June 9.
