It just had to happen, didn't it? Liverpool have been drawn against Borussia Dortmund, Jurgen Klopp's former side, in the quarter-finals of the Europa League today.
The news has of course set the internet ablaze, with Liverpool fans both delighted and appalled in equal measures.
The draw was made after Klopp's men secured their passage into the last eight at the expense of rivals Manchester United. Philippe Coutinho's superb solo effort helped the Reds claim a 1-1 draw at Old Trafford and a 3-1 aggregate win. The Reds will travel to Germany on April 7 with the return fixture taking place at Anfield one week later.
Klopp's return to the side he led to two Bundesliga titles has certainly set tongues wagging, and sent fans delving through the history books to check out the last time the two teams met.
The last competitive game between the two teams came all the way back in 2001, when they met in the Champions League group stages - and Liverpool's team was actually pretty good. Apart from the fact Emile Heskey was leading the line, of course.
Having played a 0-0 draw in the first game in Dortmund in September 2001, the Reds - managed by Gerard Houllier - ran out 2-1 winners at Anfield. The scorers? Vladimir Smicer and Stephen Wright (remember him?!), who now plays for Aberystwyth Town. A lot can happen in 15 years.
The Liverpool team who took to the field that night was: Dudek, Wright, Henchoz, Carragher, Riise, Murphy, Hamann, Gerrard, Smicer, Owen, Heskey. They would make it through the group stages before being knocked out at the quarter-final stage by another German side, Bayer Leverkusen, who would lose in the final to Real Madrid thanks to Zinedine Zidane's iconic volley.
The two teams did meet in a friendly back in 2014 when goals from Daniel Sturridge, Philippe Coutinho, Dejan Lovren and Jordan Henderson secured a 4-0 win. Ah, the glory days of the Brendan Rodgers era.
Dortmund, of course, made their way to the quarter-finals by dispatching Premier League title challengers Tottenham, with a 5-1 victory over both legs. The German club, who are hot on the heels of Bayern Munich in the Bundesliga, are current favourites to win the Europa League.
Before the draw, Klopp was asked if he was seeking a showdown against his former club. “Dortmund? Of course not!” he said. “Why should I want the strongest team in the tournament in the next round? I'm not that silly!
“But if we go there, we will try to win. I'm pretty sure there are no easy games now, we have to be prepared.”
