The Frenchman became the talk of social media when he reached behind him with his left boot to flick Alexis Sanchez's cross in off the crossbar to give the Gunners a 17th-minute lead.
While undoubtedly the best goal of the new calendar year, it has some rivals across the whole season.
Press Association Sport looks at five of the best Premier League goals this term.
JORDAN HENDERSON V CHELSEA - SEPTEMBER 16
Liverpool skipper Henderson has only scored one goal this season but it was certainly a peach
From England colleague Gary Cahill's clearance, Henderson took one touch to cushion the ball into his path before smashing an unstoppable 30-yard attempt that sailed across Chelsea goalkeeper Thibaut Courtois and into the top corner of his net in the Reds' 2-1 success at Stamford Bridge.
WILFRIED ZAHA V HULL - DECEMBER 10
If ever there was a moment where Zaha showed the type of skill which once persuaded Sir Alex Ferguson to make him his final Manchester United signing, this was it
The winger took down a cleared corner and managed to sneak between Sam Clucas and Tom Huddlestone with some excellent close control before unleashing a rocket with his right boot which flew into David Marshall's top corner.
JEFF HENDRICK V BOURNEMOUTH - DECEMBER 10
On the same day Zaha was dropping jaws in Hull, Burnley's record signing Hendrick was doing likewise in east Lancashire
The Republic of Ireland international had to stretch to even bring Matthew Lowton's through ball under his spell and from there he teed himself up before dispatching an arching 20-yard volley over Artur Boruc
His manager Sean Dyche noted: "It's just a shame we're not Arsenal because then it would be shown a 1,000 times instead of maybe four."
HENRIKH MKHITARYAN V SUNDERLAND - DECEMBER 26
Wondering where Giroud got the inspiration for his goal from? Six days earlier Manchester United's Armenian playmaker Mkhitaryan scored with a scorpion kick himself
This one was from a lower angle, closer to the goal - and Mkhitaryan was even offside as he leaned forward and blasted Zlatan Ibrahimovic's right-wing cross into the far corner of the net
It was hailed as the campaign's best strike for less than a week, though...
OLIVIER GIROUD V CRYSTAL PALACE - JANUARY 1
Giroud had already squandered one opportunity from five yards when the Gunners broke forward later in the first half on the counter attack
Sanchez's cross was actually behind Giroud but, with the big forward barely breaking stride, he contorted his body to allow him to reach it with the back of his heel and direct the ball above Wayne Hennessey and in off the underside of the crossbar
