It is an out-and-out top-of-the-table clash. PSG, the reigning European champions of the past two seasons, sit top, narrowly leading second-placed Barcelona.
After two European matchdays, they both have six points and a goal difference of seven. PSG have scored one more goal than the Spaniards, though, and thus top the bill.
Barcelona come into the match in fine form and have yet to lose a match this season in any competition.
That may well change tonight, though, as PSG are also on a frightening roll.
Last time out in the Champions League, they blew Manchester City away with a staggering first-half performance, going on to win 4-2 as Erling Haaland’s brace helped the hosts save face.
The matchday prior, they trounced the minnows Slovan Bratislava 6-1.
Barcelona’s two wins in the competition so far have come at the expense of comparatively weaker opposition in Galatasaray and Feyenoord, though the nine goals they scored across those two matches gives cause for optimism.
