It has been more than two decades since Nottingham Forest last faced Liverpool which was a Premier League clash back in 1999 that finished in a 2-2 draw.
But for the older generation of supporters, a fierce rivalry between the two teams will be reignited in the FA Cup quarter-final at the City Ground later this month.
While they are no longer going toe to toe for domestic or European honours, Liverpool have never forgotten how Forest temporarily halted the red machine in the late 70s.
Bob Paisley's side was regarded, and still are, as one of the finest teams ever to have graced English football in what was an extraordinary reign of success.
But Brian Clough's team put a stop to that by securing the league title and the European Cup against all the odds to spark an unlikely rivalry that still festers to this day.
Such was its intensity, that Liverpool fans created a chant about Forest that can still be heard from time to time both at Anfield and wherever they head on their travels.
It went: "We hate Nottingham Forest, we hate Everton too, we hate Man United but Liverpool, we love you!"
Now as the two sides prepare to go toe to toe once again for a place at Wembley in the FA Cup semi-final, we take a look back at how it all began.
New kids on the block
Liverpool fans had barely given their fellow Reds a second thought before the 1977-78 season as Forest returned to the top flight.
The two sides met for the first time in seven seasons at the City Ground on Boxing Day just as the world were starting to realise that Forest were no ordinary newly-promoted side.
Managed by Clough, a man who had immense success with Derby County five years earlier but had struggled in turbulent roles with Leeds United and Brighton & Hove Albion.
Forest were top on Christmas Day having only lost three times in their first 20 games.
However, they were yet to face Liverpool - the domestic and European champions.
Clough's side took the lead inside the first 20 minutes through Archie Gemmill, and, after Liverpool pulled level just before the break, held on the take a point.
Forest, who by this stage were already on a five-game unbeaten run in the league, would continue on that run until the end of the season and lift the title and did so by seven points, without losing a single game.
From then, the rivalry was born.
Inside or outside?
That same season, the two sides met in a League Cup final replay at Old Trafford.
Forest had beaten Leeds United emphatically in the semi-final, scoring seven goals across the two legs.
The final was decided in dramatic fashion, as Phil Thompson gave away a controversial penalty early in the second half that would allow John Robertson the chance to convert and win the cup for Forest.
Replays at full-time showed that Thompson had deliberately fouled John O'Hare outside the penalty area to avoid giving away a penalty, but O'Hare had fallen inside.
To this day, they've never forgiven him.
After full-time Thompson said: "There was no way i could get to it (the ball).
"John O'Hare would have scored so I brought him down. It was my only chance to get him.
"I had to pull him down. It was a professional foul.
"I know it sounds bad, but I had to kick him outside the box.
"Obvious penalty," said Forest assistant boss Peter Taylor.
"Nobody is doubting it, surely?"
However, after being told that replays had shown that the foul was committed outside the area, Taylor famously added: "They (the cameras) also show that we have the cup, that's the main thing."
European Cup clash
After winning the title, Forest's stars were dreaming of exotic trips abroad in the European Cup, but instead drew Liverpool in the opening round.
Neither side could have had a tougher first-round tie, but it would be Forest who edged it by thanks to a 2-0 first-leg win at the City Ground.
Liverpool were, however, unstoppable in the league and cruised to yet another title by a margin of eight points, but it was Clough's Forest which went on to lift the European Cup.
One year without defeat
Victory away at Bolton later than year meant that the Reds had made it an entire calendar year without defeat in the league, just before their trip to Anfield.
Liverpool were more determined than ever to end Forest's unbeaten run and, spurred on by a battle with rivals Everton at the top of the table, two goals from Terry McDermott meant that Forest's unbeaten run under Clough would come to end at one year and 14 days.
The 2-0 win helped Paisley to another league title, as Liverpool yet again dominated English football while Forest retained the European Cup.
The end of a fierce but fleeting rivalry
After lifting the European Cup in 1980, Forest would go without silverware for eight years and without ever mounting a serious challenge for a league title.
Liverpool on the other hand, finished either first or second in the top flight 18 out of 19 seasons across the seventies and eighties, winning eleven 11 titles along the way.
Nevertheless, the two sides would still share some unforgettable encounters over the years that followed.
