Paris Saint-Germain are not traditionally a force in Europe, but an outlandish spending spree over the past two seasons has bought them an opportunity to surprise Europe's very best, FC Barcelona.
The Catalans have been reinstated as tournament favourites after Lionel Messi inspired a sensational comeback at the Camp Nou to overcome Italian giants AC Milan.
While PSG is a favourable draw for Barcelona, the French team have really found a groove of their own in recent months.
They will be buoyed by the recent news that their talisman, Zlatan Ibrahimovic, is now clear to play after having his match ban reduced. The big Swede's colourful history with Barca adds a tantalising sub-plot to this exciting fixture.
A talent like Ibrahimovic is a threat to any team, but against a side like Barca, he could find himself isolated.
PSG's biggest threats lie elsewhere.
