Sunderland are officially the worst Premier League team in history - and Arsenal made them look every inch like it with a good old fashioned hiding at the Stadium of Light.
Bar an all-too-brief six minutes in the second half the Gunners comprehensively outclassed the winless Black Cats to leave them rooted to the very foot of the table.
With two points after 10 games no team has EVER started worse.
And David Moyes' team looked every bit like relegation certainties as Alexis Sanchez and Olivier Giroud both helped themselves to braces as the Gunners moved top with ease.
Here are 5 things we learned:
1. Oxlade-Chamberlain may FINALLY be fulfilling his potential
Arsenal fans have long been waiting for Oxlade-Chamberlain to really arrive , but after two goals in midweek and another excellent display here that time may finally be here.
Given the chance to start by Theo Walcott's injury the England man grabbed it with both hands, excelling throughout.
His cross for Sanchez's opener was a beauty and his speed of thought and movement gave the Black Cats back four fits all afternoon long.
From both an Arsenal and England point of view it's great to see.
2. Why have one No.9 when you can have two
Such is the class of the man Alexis can virtually play anywhere in the offensive half of the field.
The Chilean was an absolute menace against Sunderland, buzzing all over the field, at the heart of everything Arsenal did well.
While you always expect him to be a focal point and the principle attacking threat, he also linked play and held up the ball superbly too.
But just when you thought Sanchez had made the Gunners' troublesome striking role his own, Giroud comes on and shows he isn't going anywhere yet.
The Frenchman clambered off the bench to score twice in five minutes to quell Sunderland's brief dalliance with parity in the game.
He took both goals with customary elegance and added the extra physicality that the Gunners lack with Sanchez alone up top.
If the Gunners are to end their infamous title drought they need a bona fide 20-goal No.9 - they might now have two.
3. Kone must earn his money
You could argue Sunderland's biggest signing this summer was a player they already had.
Lamine Kone was linked with a move away throughout the transfer window before he finally put pen to paper on a highly-lucrative new deal worth a cool £90,000-per-week.
It's now high time he earned it.
The big Ivorian was caught ball watching for Sanchez's first goal and was given the runaround all day by the electric Chilean, which included him bringing him down for what should've been a Gunners penalty.
Sunderland need all the help they can get in their current plight, especially from a player being so handsomely rewarded.
4. No Xhaka, no problem
Wenger could've been forgiven for being a little concerned when he pondered his midfield options ahead of this lunchtime's game.
With Granit Xhaka suspended, Santi Cazorla injured and Aaron Ramsey not yet back to full fitness, Wenger was uncharacteristically light in the middle of the park.
But he needn't have worried - the duo of Francis Coquelin and Mohamed Elneny dominated the midfield third winning the ball back and distributing it further forward to Oxlade-Chamberlain, Mesut Ozil and Alex Iwobi effectively and consistently all afternoon.
5. Sunderland are down
Remember that Derby County team of 2007/08? They had five points by now - this Sunderland team have two.
It all looks very bleak for the Black Cats and boss David Moyes.
Yes, today against Arsenal was never circled as a home banker in the manager's diary, but following a decent enough opening 20 minutes they collapsed thereafter never looking anywhere worthy of anything other than another defeat.
Moyes is in real trouble - they remain the only club in the __football League without a win and the truth is they don't look anywhere near getting one.
The home faithful seem resigned and who can blame them.
