Liverpool players slumped to the turf in disappointment as the fates and fortunes of the Champions League were illustrated in this thrilling last-16 tie that provoked all the emotions on a classic European night at Anfield.
Arne Slot's side have barely broken stride as they topped the Champions League table and raced 15 points clear in the Premier League - but this is the biggest setback Liverpool and their Dutch coach have suffered this season.
Ironically, Liverpool played much better in defeat at Anfield then they did when winning in the Parc des Princes in the first leg, but that was no consolation as this time luck did not smile on them as they were denied by the woodwork and then on penalties, when Donnarumma's expertise came to the fore.
And most of all, they were frustrated by a top-class PSG side who are shaping up as potential Champions League winners.
Anfield provided its usual thunderous atmosphere but Liverpool could not quite deliver, looking leggy and second best in the added 30 minutes.
Liverpool will need to recover swiftly, with the Carabao Cup final against Newcastle United at Wembley on Sunday, but this was a defeat that will hurt deeply as they would have had Champions League expectations far beyond the last 16.
