Back in October 2001, Gérard Houllier's Liverpool hosted Borussia Dortmund in the group stages of the Champions League, and the men in red ran out 2-0 winners on the night, just over a month after both sides played out a 0-0 draw in Germany.
Liverpool were the reigning UEFA Cup champions, and would go on to finish 2nd in the Premier League and reach the Champions League quarter-finals that year, while Dortmund made up for a disappointing group stage exit by winning the Bundesliga.
Looking back on the squads that started that match, there are some fantastic names in there and it is incredibly satisfying to reminisce ahead of their meeting in the Europa League.
Both teams playing essentially a traditional 4-4-2, let's look at some of the players on show.
What Liverpool fans wouldn't give to have their much loved Pole in goal these days instead of their blundering Belgian... Dudek's ability to rise to the occasion was symbolic of the entertaining Liverpool side of that time.
In five years at Anfield, English full back Stephen Wright made 17 first team appearances before moving to Sunderland, and then slowly moving down the divisions in English football. He still plays today with Aberystwyth Town.
Before he became somewhat of an unfortunate internet meme, he occasionally scored goals for Liverpool and also occasionally celebrated them with a DJ style gesture. His record of 13 goals in 54 appearances that season was a sign that he was never going to be the striker Liverpool needed him to be.
The divisive German keeper was massive for Dortmund that year en route to a league title, but he wouldn't be sticking around long as Arsene Wenger brought him to Arsenal in 2003, where he would prove to be an excellent replacement for David Seaman.
An iconic figure of the incredibly enjoyable Nigerian teams of the 90s, and scorer of a historic goal against Spain at the 1998 World Cup. After a nightmare spell at Juventus, Oliseh got his career back on track with the black and yellow.
An unmistakable giant of a man who gave Ireland some problems on a few occasions, Koller was well marshalled home and away by Stephane Henchoz, despite the great disparity in size.
Here's hoping for two great legs when these sides meet again.
