Arsenal set a new club record for their largest-ever Premier League away win in their 6-0 obliteration of London rivals West Ham United at the London Stadium.
Mikel Arteta's men had already fallen to the Irons' superiority twice this season, losing 3-1 in the fourth round of the EFL Cup before a shock 2-0 Emirates defeat in the Premier League in December.
However, David Moyes's men went into Sunday's London derby having not won another game since that success over the Gunners, and they were torn to shreds in a historic afternoon in the capital.
Arsenal were not able to unlock the door straight away, but the visitors' deserved opener arrived when William Saliba headed home from a Declan Rice corner, which sparked an unrelenting barrage of attacks from the electrifying visitors.
Bukayo Saka's penalty, Gabriel Magalhaes's header and Leandro Trossard's curler propelled Arsenal into a stunning 4-0 advantage by half time, seeing the Gunners lead a Premier League away game by at least four goals at the break for the first time since their 4-4 draw with Newcastle United in 2011.
There would be no such capitulation from the North London giants this time around, though, as Saka fired home the visitors' fifth before ex-West Ham captain Rice returned to haunt his former employers with a sixth from long range.
By virtue of putting six past Moyes's meek men without reply, Arsenal have registered their biggest away win in Premier League history, as well as their joint-largest away success in league history.
Prior to Sunday's slaying, Arsenal's previous best away wins in the Premier League were 6-1 batterings of Middlesbrough and Everton, the latter of which occurred in 2009 with Moyes in charge of the Toffees.
The Gunners have also equalled their biggest league victory of all time on the road - a 7-1 crushing of Aston Villa in 1935 - while West Ham's six-goal defeat marked their joint-heaviest loss in league history.
Personal achievements were also the order of the day at the London Stadium, where Odegaard became the first player on record in the Premier League to complete at least 100 passes, create at least five chances and set up multiple goals in one game.
In addition, Saka hit the 50-goal mark for Arsenal at just 22 years old, becoming the youngest player since Frank Stapleton in 1978 to achieve a half-century of strikes for the Gunners.
"To be honest, I'm really happy to achieve that, but I'm not sure I can be happy today. I missed some chances that I thought I could have scored, you know, but obviously it's a great achievement, so I'm proud of that," Saka told Sky Sports News after the game.
"We were 4-0 up in the first half and we could have scored many more including myself, we smelled blood today and we went for the kill. We did really well to score more and yeah we're happy."
Arsenal's emphatic win makes no difference to their third-placed ranking in the Premier League table, but the Gunners have made up their goal difference to Manchester City, who are now only leading Arteta's men on goals scored with a game in hand.
Arteta's men have five full days to recover before they go again at home to Burnley next Saturday afternoon. body check tags ::
