Iwobi opened scoring for the Gunners 16 minutes into the game. The Super Eagles winger was left unmarked at the far post as a deep cross came into the penalty area from Kolasinac.
Iwobi volleyed the ball towards goal, it took a big deflection off Kongolo and bounced into the back of the net.
While Lacazette doubled the lead just before half-time 44 minutes into the game.
Huddersfield kept pressing in the second half and played well, but they just couldn’t get the ball into the back of the net, with Leno pulling off couple of good saves and the woodwork denying the hosts.
90′ + 3′ minutes, Huddersfield pulled a late consolation goal to make the scoreline 2-1. Diakhaby got into the box and his shot bounced up off Leno and towards goal, but the final touch came off Kolasinac under pressure from Bacuna.
The victory for Arsenal put them level on points with Chelsea in fifth and just one point behind Manchester United in fourth place.
The Gunners will now battle BATE during the Europa League knockout stages on Thursday.
Meanwhile Huddersfield remain rooted to the bottom of the table, 13 points from safety and they travel to Newcastle next weekend.
LIVERPOOL BACK TO WINNING WAYS:
Liverpool returned to winning ways, after comiing out 3-0 winners over Bournemouth with a brilliant performance that saw them dominate for the majority of the game.
Mane opened the scoring in the first half with a powerful header, before Wijnaldum doubled their lead with a wonderful chipped effort over the goalkeeper.
They continued to improve in the second half and got their third goal of the game through Mohammed Salah, which secured them the points. The Reds could’ve had more if not for some excellent saves from Boruc as well as Salah’s effort that rebounded off the crossbar. Bournemouth did have a couple of chances, but they didn’t trouble Liverpool enough to get onto the scoresheet.
So, Liverpool go back to the top of the Premier League table with that win until tomorrow at least when Manchester City face Chelsea. They are now unbeaten in their last five matches in the league, and get a bit of a break from the competition as they prepare to face Bayern Munich in the Champions League.
Bournemouth drop down to 11th with that loss due to West Ham’s draw and their inferior goal difference and will be hoping to bounce back from their recent drop in form when they face Watford in their next match.
