Manchester United are set to wear our black third kit when we take on Arsenal at the Emirates Stadium on Sunday.
It will be a fourth outing of the season for our alternative jersey, with mixed results so far following the win at Wolves, a draw against Nottingham Forest and our reverse to Brentford.
With Arsenal turning out in their traditional red-and-white number, black is the only choice for the next Premier League outing - and it's a selection that evokes some powerful memories from previous iterations of this evocative fixture.
For me, the most obvious starting point is the 2004/05 clash at Highbury, our penultimate league visit to Arsenal's cramped but grandiose former home.
That was the night when Roy Keane and Patrick Vieira - the two finest central midfielders of their generation - went head-to-head in the tunnel, as English football's foremost rivalry threatened to boil over, following years of simmering, bubbling resentment.
What followed was arguably the last truly great clash of the Ferguson and Wenger era.
There were to be eight more seasons of duels between the two managers, but this blood-and-thunder encounter is seen by many as the closing of a chapter, three months before Chelsea broke the United-Arsenal stranglehold on the title.
The Gunners led at half-time, 2-1, and watching the match back you're struck by how physical it is, with referee Graham Poll letting several challenges go that would surely be contenders for straight reds in the modern game.
United's youthful verve in attack eventually won the day, with Cristiano Ronaldo scoring twice before Mikael Silvestre's sending off, for a headbutt on Freddie Ljungberg.
John O'Shea then capped a marvellous victory with a sumptuous chip that defied his categorisation as a player.
Although we'd eventually finish third behind our two challengers from the capital, that night is still fondly remembered as a fitting denouement - by the time the sides met again in the top-flight, Keane and Vieira had departed.
Arsenal moved to the Emirates Stadium in 2006 and, being honest, our record there isn't brilliant - especially during Mikel Arteta's stint as Gunners boss.
Hopefully that can change at the weekend but, for now, two matches stand out when United have worn black.
In 2010, the year after a Champions League semi-final masterclass, the Reds showed our counter-attacking best to defy the Londoners again, as Nani, Wayne Rooney and Ji-sung Park all scored.
There was a fine success to cherish under Jose Mourinho nine years ago too, as we raced into an early lead and then had David De Gea to thank for making a succession of great saves in a 3-1 win.
That is our most recent league victory in N7 and, on Sunday, Michael Carrick's men will be looking to end a run of four straight top-flight defeats there.
