Just a few hours after France knocked Argentina out of the FIFA 2018, sending Lionel Messi home empty-handed following a seven-goal thriller, Edinson Cavani scored twice as Uruguay shattered Cristiano Ronaldo's World Cup dream with a 2-1 victory over Portugal in Sochi on Saturday.
Paris Saint-Germain striker Cavani curled home a superb 62nd-minute winner to settle a thrilling second-round duel in Sochi which sent Uruguay into a quarter-final against France next Friday.
Cavani had already put Uruguay in front early on, only for Pepe to head Portugal level in the 55th minute in a thrilling contest that was not the battle of attrition many predicted.
Pepe's goal was the first time the South Americans' defence had been breached in this tournament, but they stood firm after that and are beginning to look like genuine contenders moving into the latter stages in Russia.
The only downside for Oscar Tabarez's side was the sight of Cavani limping off late on, raising a question mark over his fitness for next week's last eight showdown with the French in Nizhny Novgorod.
Meanwhile, European champions Portugal go home, as Ronaldo and Lionel Messi bow out of the competition on the same day.
In contrast, Uruguay march on with arguably the best defence in international football and one of the best strike pairings anywhere.
Suarez and Cavani combined brilliantly for the seventh-minute opener on Russia's Black Sea coast.
Cavani picked out Suarez on the left with a cross-field ball, before continuing his run into the penalty area and meeting the Barcelona striker's return delivery at the back post, the ball smacking off his face and flying in.
Suarez almost doubled the lead from a free-kick midway through the first half that forced a good save from Rui Patricio.
Meanwhile, Ronaldo did not touch the ball once in the opposition area in the first period. But with Uruguay sitting back, Portugal did equalise 10 minutes into the second half.
A corner was played short to Raphael Guerreiro, and his cross from the left was headed home from close range by Pepe, rising high above Diego Godin in the area.
After nearly five and a half hours of football, it was the first goal Uruguay had let in at this World Cup -- indeed it was the first they had conceded in 2018.
But their response to that was magnificent as they went quickly retook the lead, Rodrigo Bentancur teeing up Cavani for a magnificent first-time curling strike into the far corner on his right foot.
Portugal coach Fernando Santos threw up his hands in disgust, realising that coming from behind a second time against this Uruguay defence was going to be a tall order.
Goalkeeper Fernando Muslera did almost gift them another equaliser, dropping a high ball at the feet of Bernardo Silva, but the Manchester City man could only volley over.
Cavani then had to be helped off by Ronaldo before watching the rest of the game from the dugout with ice on a calf injury.
The 1998 champions France won 4-3 and looked a different side from the one that struggled to find their cutting edge in the group stage, pouring forward with pace and purpose to stretch the ageing Argentine defence in Kazan.
Antoine Griezmann gave France the lead from the penalty spot but the South Americans levelled after a sweet hit from Angel Di Maria and edged ahead shortly after half-time through Gabriel Mercado.
But defender Benjamin Pavard equalised with a thunderous strike to pull France level and once more change the complexion of the game.
That set the scene for 19-year-old Mbappe, who netted two goals in four second-half minutes to become the first teenager to score at least twice in a World Cup match since Pele in 1958.
Sergio Aguero gave Argentina late hope but they ran out of time and head home after a rollercoaster ride in Russia that ultimately ends in bitter disappointment for the two-times former champions.
Man-of-the-match Mbappe brushed off the Pele comparisons.
"I'm very happy and it's flattering to be the second teenager (to score twice in the knock-out rounds) after Pele but let's put things in context: Pele is in another category, but it's good to be among these people," he said.
