Drawn as the so-called 'Group of Death' back in August, Group F certainly lived up to the moniker as two of its graduates meet again in UEFA Champions League semi finals.
Battling against Newcastle and AC Milan, both Borussia Dortmund and PSG emerged from the group eventually, with the Black and Yellows defying expectations to top the group.
And if there's one thing that can be labelled at Dortmund's season thus far, it's unpredictability.
Now five points astray of fourth place in the Bundesliga following a limp 4-1 defeat at the hands of RB Leipzig this past weekend, their European campaign hasn't replicated the domestic inconsistencies.
A triumphant comeback at home to Atletico Madrid last time out epitomised the spirit they have shown on the continent, particularly at home. They remain unbeaten at Signal Iduna Park in this tournament.
Meanwhile, PSG have - as is usually expected - had little trouble within France, sealing a third straight Ligue 1 title (as AS Monaco dropped points at Lyon) and reaching the Coupe de France final.
Similarly, Luis Enrique's men disposed of Spanish opposition in Real Sociedad and Barcelona relatively comfortably during the Champions League knockout stages.
The French champions started their European campaign with a 2-0 win over Dortmund in Paris, but drew 1-1 in the reverse fixture on matchday six.
In fact, PSG have yet to win in Dortmund. They again drew 1-1 back in the 2010/11 UEFA Europa League and lost their previous Champions League knockout stage visit 2-1 due to a little known striker named Erling Haaland.
The Champions League is the one thing that has alluded PSG ever since the Qatari-backed takeover in 2011 infused them with untold riches.
It's far from plain sailing against Edin Terzic's side, who will likely thrive as the underdog, but, should this match go their way, Kylian Mbappe's last hurrah could yet end in that coveted glory.

Team News
Centre back Mats Hummels is in line to play despite coming off early in the loss to Leipzig. Ian Maatsen and Emre Can return after serving suspensions on Saturday.
Quarter final hero Marcel Sabitzer has resumed training as has Donyell Malen, who missed both legs against Atletico Madrid. Terzic said he "assumes" both will be available.
Julien Duranville has a muscle injury while the first leg will come too soon for striker Sebastian Haller to feature.
Presnel Kimpembe has returned to training recently, but will remain out. Layvin Kurzawa and Sergio Rico are long term absentees.
There are no further injury concerns for the Parisians, who had the luxury of resting some key players in the 3-3 draw to Le Havre.

Key Players
Borussia Dortmund: Jadon Sancho
Just as only the boldest of fortune tellers would have predicted Dortmund to reach the semi finals of the Champions League, merely a select few of them could have foreseen Jadon Sancho being part of the journey.
Starting the season bereft of form at Manchester United, the England international has shown a remarkable upturn in confidence and performances since re-joining BVB on loan.
Lamine Yamal's tricky wing play greatly troubled Nuno Mendes in the quarter finals, and Sancho is more than capable of exploiting the 1v1s in a similar fashion.
There was occasional space in behind the full backs in Barcelona, which the winger could flourish in, especially if Enrique opts for a more forthright midfield.
Fresh from scoring his fortieth Bundesliga goal - making him the highest scoring English player in the league's history - he will be integral to any damage Dortmund inflict on their counterparts.
PSG: Kylian Mbappe
For some players, you need only mention their name to justify why they will be the difference makers. Mbappe is undoubtedly one of those individuals.
Forty-three goals in forty-four games - including eight in ten Champions League matches - has propelled PSG to a potential treble in his final year with the club.
It will be an interesting task for the Frenchman, up against the bullish experience of Mats Hummels and the pacey athleticism of Nico Schlotterbeck.
While he did not score himself, there were a plethora of chances for Mbappe last time the teams met at the Westfalenstadion, and the hosts have not kept a clean sheet at home since March against PSV Eindhoven (but did concede 17 shots and 1.5 xG)
Gunning for his first European winners medal, it's difficult to see how he will be kept as quiet this time around.
