While their unbeaten run that now stands at 21 matches was rarely under threat, Arsenal had to demonstrate a self-belief and tenacity that had largely been missing until Emery's appointment as manager. The game was frustrating one for the Gunners as Huddersfield tried it's best to the home team. Our goals have been coming later.
Arsenal's players will be "reminded of their responsibilities" by the club after a string of first-teamers were alleged to have inhaled nitrous oxide at a pre-season party.
"It was important for us to win today".
"It was a tough match, it was a slow rhythm but we want it and I think we deserved to win".
Granit Xhaka, Shkodran Mustafi and Matteo Guendouzi were all cautioned by referee Paul Tierney, who ruled that the trio had dived with the intention of tricking the referee into making a decision.
Alexandre Lacazette and Aubameyang were paired together and both strikers spurned clear chances within a minute just before the half-hour mark.
On whether his players are becoming more adaptable in changing systems he admitted: "We are preparing differently and tactically".
On Ozil's possible return, Emery said: "This morning he worked with the physiotherapist on the pitch, running and touching the ball".
Having shown signs of improvement, Huddersfield remain in the bottom three following successive defeats by Brighton, Bournemouth and Arsenal.
Huddersfield were also forced into two alterations in quick succession due to injury, and between the two substitutions Alex Pritchard was denied a penalty when he claimed Hector Bellerin clipped him.
"Huddersfield manager David Wagner said:" I think if you concede so late in a game it is disappointing.
"Penalty appeals - this is why I don't like to comment".
"But I can see the positives". He made sure we jumped back into the Top Four, andI must say I'm not too upset that Chelsea beat he Moneybags, but I am now going to cheer on Leicester until I am hoarse! "Defensively we looked very solid".
