In-from Arsenal registered their 12th consecutive home league win as they hammered newly promoted Huddersfield side on Wednesday night.
Alex Lacazette opened the scoring inside three minutes after a neat flick by Aaron Ramsey but the visitors from Yorkshire refused to crumble.
Lacazette was unable to complete the game after picking up a groin injury in the first-half which the Arsenal boss admits will rule him out of Saturday's clash against Manchester United.
Olivier Giroud came on to replace him and scored twice, his first was a near-post finish to convert a wonderful move of slick passes orchestrated by Mesut Ozil, who could simply do no wrong during this golden phase of the second-half.
Alexis Sanchez swept in number three on the half-volley from another Ozil cross from the right.
'I was not pleased with everything,' said Wenger. 'We stated well and slowly we lost the urgency in our game and in the second-half we gave them one or two chances.
'We missed the second and at 1-0 we played with a big fear. The pass didn't come early enough and we were inhibited.
'When we scored the second everyone was suddenly in the mood, passing it quicker. It became difficult for Huddersfield and they collapsed a little bit. We played with freedom, drive and creativity. And our link play was fantastic to watch in the last 20 minutes.'
Ozil then found the net, a popular and deserved goal which was finished with a typically casual dink over goalkeeper Jonas Lossl following Ramsey's forward pass.
Ramsey and Granit Xhaka excelled in Arsenal's midfield but it was Ozil's name which was sung heartily around the Emirates Stadium.
Giroud completed the romp with his second in the 87th minute assisted by a rampaging run by Sead Kolasinac into the penalty area.
Manchester City yesterday extended their unbeaten run in the English Premier League with a 2-1 win over Southampton thanks to Raheem Sterling's late goal.
Kevin de Bruyne opened the scoring for City two minutes after the break before Oriol Romou restored parity minutes later. However, Sterling's goal deep into added time all but secure three points for City.
Mohammed Salah stuck twice as Liverpool beat Stoke City three nil while Chelsea were one nil winners over Swansea at the Bridge.
