Having lost the first leg 4-1 at the Camp Nou, Barcelona needed at least four goals of their own at the Parc des Princes on Wednesday to have a shot at progressing. They only managed one.
Lionel Messi's golazo - a wondrous, swerving strike into the top corner - was all Barcelona got. It was not the start of a comeback, though it may have seemed like it the moment it cannoned in. It was merely the equalizer in an eventual 1-1 draw, the most spectacular of meaningless goals. Messi missed a penalty minutes later. Hopes faded after that.
PSG advanced 5-2 on aggregate, and Barcelona fell in the round of 16 of the Champions League, the earliest they've tumbled out of the competition since the 2006-07 season.
And for the first time since the 2004-05 campaign, the Champions League will move on to the quarterfinals without Messi or Cristiano Ronaldo, potentially marking the end of an era. Ronaldo's Juventus were eliminated by Porto on Tuesday.
Kylian Mbappe gave PSG the lead in the 31st minute with a well-executed penalty kick. It was his fourth goal against Barcelona across 180 minutes of play.
The visitors created enough chances to get back into the tie. Ousmane Dembele botched several opportunities, including a golden chance on a partial breakaway that PSG defender Presnel Kimpembe successfully defended, and goalkeeper Keylor Navas stopped Messi's spot-kick in first-half stoppage time, one of nine saves on the night.
The tempo Barcelona set in the first half slowly diminished in the second. At the hour mark, Messi tried to poke home a loose ball in the six-yard box, only to have PSG captain Marquinhos produce a crucial block.
