Caltex Socceroo Aaron Mooy could do little to halt the Gunners who blew away Huddersfield with a red-hot second half performance to win 5-0 in the English Premier League overnight.
After Lacazette gave Arsenal an early lead, three goals in quick succession in the second half to Sanchez, Giroud and Ozil ended Huddersfield's resistance after the score was 1-0 to the hosts at half-time.
Giroud added his second and Arsenal's fifth late in the night at the Emirates to cap off a dominant night for Arsene Wenger's men.
To compound a poor evening for the Terriers, Mooy was booked on the hour mark for a tackle on Arsenal's Granit Xhaka.
The World Cup-bound Aussie was subbed off in the 74th minute with the game seemingly out of reach for Town.
Huddersfield, in 13th place in the Premier League, next face Everton away this weekend.
