Kylian Mbappe's 70th-minute penalty gave France a 1-0 victory over Paraguay in an ill-tempered World Cup last-16 tie in Philadelphia to set up a quarter-final meeting with Morocco.
Mbappe converted his kick coolly despite Paraguayan attempts to put him off as he finally broke the South American side's resistance and moved level with Lionel Messi on seven World Cup goals.
Paraguay, winners over Germany in the previous round, had defended stubbornly in the 39-degree heat up until then, restricting France, the tournament's outstanding team so far, to long-range shots and succeeding in slowing the game down.
It took the introduction of Desire Doue for Bradley Barcola for France to find a way through. Uzbek referee Ilgiz Tantashev waved away his penalty appeal initially after he was tripped by Diego Gomez but overturned the decision after a VAR check.
Paraguay players attempted to delay the penalty and scuff up the spot but Mbappe held his nerve to find the bottom corner.
Paraguay's frustration spilled over with some reckless challenges in the closing stages, most of which went unpunished by the referee, who didn't give Paraguay any bookings despite France's protests and a series of confrontations between players which continued after the final whistle.
Mbappe, a target for Paraguay throughout, was denied a second goal by a superb double save from Orlando Gill in stoppage time and subsequently refused to shake the goalkeeper's hand after Tantashev had called time on a combustible contest - and a bewildering refereeing performance.
France boss Didier Deschamps said: "It wasn't easy. If we'd taken one of our chances late in the game, it would have been a much more comfortable finish.
"Paraguay use every trick in the book. It's not necessarily the kind of football people enjoy watching, but we stayed focused and that's not easy to do.
"They're a physical side and they defend very well. It's another important step forward. It's always difficult against South American teams, but I'm delighted that the players got the job done.
"We're into the quarter-finals and we have to enjoy that."
France captain Kylian Mbappe said: "We knew what kind of match to expect. I think it was really good for us to experience a game like that and to see how we handled it.
"We showed that we're not just a team capable of playing attacking football. Every team uses its own strengths - there's no right or wrong way to play.
"The only right way is to win. Now we have to focus on Morocco. We're really looking forward to facing them because we know they're a very good team."
France will face Morocco in the World Cup quarter-finals, in a repeat of their 2022 semi, on Thursday July 9, kick-off 9pm (BST) in Boston.
