The Gunners led with an Alexandre Lacazette goal just three minutes into the game but had to wait for their second until the 68<sup>th minute after which the floodgates opened. Olivier Giroud, Alexis Sanchez and Mesut Ozil scored three goals in five minutes to put the game beyond the Terriers and the former of the aforementioned trio netted his second with three minutes to go to complete the rout.
The scoreline, however, did not paint the full picture of the game, as Arsenal's defence was put under pressure by David Wagner's team in both halves. Petr Cech was called into action on more than one occasion after some lax defending from the Gunners.
Wenger was not pleased that his team took their foot off the pedal after scoring an early opener and believes they gave chances to their opponents to get back in the game. The second goal was a much-needed relief after which the floodgates opened and the game was wrapped up with some clinical passing and finishing.
"I felt that I was not pleased with everything, but we started well and I think after that we slowly lot a bit of our edge, the urgency in our game and a little bit as well in the second half we gave them one or two chances," Wenger said after the 5-0 win, as quoted on Arsenal's official site.
"We missed as well the second goal, but after that once we scored we played with freedom, with drive, with creativity and our link play became fantastic to watch in the last 20 minutes.
"I'm convinced that we played with a bit of fear at one-nil at some stage because we didn't play with the freedom, the passes didn't come early enough," the French coach added.
"We played a bit inhibited and when we scored the second goal everybody was suddenly had more movement and passed the ball quicker, they struggled as well maybe and thought that was game over. Maybe we benefited as well from the fact that they had to give a lot for 70 minutes and they collapsed a little bit in the last 20."
Wenger had special praise for Ozil, who scored one and assisted two, while Aaron Ramsey also added a pair of assists to continue his good form. There was, however, one disappointment ahead of Arsenal's clash against Manchester United at the weekend as the Gunners' top marksman Alexandre Lacazette picked up a groin injury and is facing a few weeks on the sidelines.
