It is nine years to the day since Paul Scholes scored an unforgettable screamer against Barcelona to give Manchester United a 1-0 aggregate win over Barcelona and book their place in the 2008 Champions League final in Moscow.
That goal will always be the lasting memory from the tie, but United found themselves under a lot of pressure in both the home and away legs as Barcelona were on the verge of becoming an irresistible force in European football.
But resist is exactly what Alex Ferguson's men did, and it was largely down to the tactical advice of assistant manager Carlos Queiroz. It was only after the Portuguese left Manchester United that his value was truly appreciated, as he was the man behind the tactial setups deployed, particularly in Europe.
Speaking to Paul Merson for Sky Sports' Fantasy Football Club, Michael Carrick revealed how Queiroz drilled the heart of United's 4-4-2 into nullifying Barcelona's main threat.
We were playing relentless games because of the league and the Champions League, we didn't really have time to train physically and do a lot of work, but Carlos Queiroz lead the session and he's brought two gym mats out onto the pitch.
We'd normally do situps on them, but he's put them on the pitch and slung them down just - it was me and Scholesy in midfield and I think Rio and Wes Brown were centre-halves - and he's put these two mats in between us, we're thinking; what's he up to here?
Literally for about five minutes he's just said don't let the ball get on those mats, so straight away you switch on and you're blocking that space off, that's where Barcelona, around the edge of the box, that's where they wanted to get into, that space, that was how they played at the time.
We played 4-4-2, two banks of four, blocked off that space, got a 0-0 draw at Barcelona and obviously managed to beat them at Old Trafford. Just little things like that make you think.
Under Ferguson, United were comfortable enough in imposing their style of play on lesser teams, but when it came to the big games there was often a tactical surprise or two planned, and Queiroz was often the man behind it.
Many fans yearn for the days when he and Ferguson were plotting the shape and structure of the Man Utd side, but it's clear that he left an impression on the players too.
And, just because it would be rude not to, here's that absolute peach from Paul Scholes once again.
