Do yourself a favour and watch the video above from Arsenal v Chelsea in the Champions League quarter finals from April 6 2004 (and how old does that date make you feel?)
Highbury – remember that place?
Tuesday night Champions League action – OK, don't get too teary and nostalgic.
Three minutes to go.
If your knowledge of Chelsea Football Club commenced on that day, a dozen years ago, you would be forgiven for thinking Arsenal had been the Blues' whipping boys for an eternity.
Notwithstanding this season's calamity at The Emirates, there has been a decade and more of almost untarnished superiority over our friends from up the Piccadilly Line.
It wasn't always thus: and when Chelsea went to the grand old halls off Gillespie Road, for the quarter final second leg in the 2004 Champions League, the omens were not good.
Highbury had been a barren hunting ground for some time: ignoring the 0-5 romp over Gunners' reserves in the League Cup in 1998, Chelsea had not won there in 24 years.
Add to that: this was the famous Invincibles – unbeatable all season in the Premier League, and arguably the best side in Europe right then.
The first leg, at Stamford Bridge, ended 1-1. The second looked to be going exactly the same way, with extra time seeming a certainty.
Cometh the hour, cometh the man.
Wayne Bridge had been one of Chelsea's first signings under new owner Roman Abramovich.
He soared down the left, and played a one-two with Eidur Gudjohnsen: the Icelander giving the ball the deftest of flicks, showing his forever enduring magnificent reading of a game.
And Bridge fired past Jens Lehmann – sending Chelsea into the semi finals.
As Arsenal faces (and bodies) fell, knowing they were beat, Bridge ran – and ran, and ran.
His face was the face of a small boy, painted with glee.
Claudio Ranieri, whose changes that night (notably the introduction of Jesper Gronkjaer) had turned the game, looked stunned: punching the air over and over and over.
Bridge had broken the hoodoo: Arsenal were no longer unbeatable; they had become the ordinary London neighbours Chelsea have known almost ever since.
It was to be the moment of the season for Chelsea: Ranieri's tinkering imploded in the Monaco semi, and he collected his cards not long after.
Bridge never really fitted in under new man Jose Mourinho: his pursuit of Highbury opponent Ashley Cole, both blatant and unlawful, would eventually give Chelsea the best fullback the club had ever had.
Bridge settled into a routine of being second best, and his career would dwindle out via various loan deals, and much bench time.
There was also the personal business between he and John Terry.
These days the binary nature of social media requires people to take one of two sides in any such matter: like friends of a divorcing couple who often seem able only to accept the case of one party over the other.
Everyone had to be either Team Bridge or Team Terry – and the Captain, Leader, Legend was never going to lose that one.
The greater truth, of course, is that neither man's on-pitch contribution was diminished by the petty squabble.
In reality, most Blues know that: anyone who was at Highbury that night, in body or spirit, will remember one of the most iconic goals of our lifetimes – a moment that brought no less than pure joy.
Over coming weeks we'll see a different side to Bridge: breakfasting on kangaroo parts, and bathing in beetle juice.
We may even hear a bit about his Chelsea past: it's the main reason the broadcasters pay these minor celebs so much cash, to spill the beans behind headlines we have read.
But, whatever transpires, Bridge will always be one of the heroes of Highbury: not a Chelsea legend, or even especially a great, but a man very fondly remembered for a moment that will live on forever.
We know what he can do on an April night in north London: now it's time to find out how he can transfer those skills to a Bushtucker Trial.
