Mbappe stars as France progress, Cavani shines for Uruguay
France overcame Argentina 4-3 in Kazan whilst Uruguay defeated Portugal 2-1 in Sochi.
Kylian Mbappe stole the show in Kazan, scoring two fine goals that gave France victory in a thrilling World Cup encounter with Argentina.
Antoine Griezmann put the French ahead with an early penalty before Angel Di Maria and Gabriel Mercado netted either side of the half for Argentina.
Les Bleus equalised in stunning fashion through Stuttgart defender Benjamin Pavard before Mbappe added two to ensure France progressed into the quarter-finals.
Substitute Sergio Aguero grabbed a stoppage time consolation to ensure the game finished 4-3 - the first time that scoreline has happened in a 90-minute World Cup match.
The victory saw France manager Didier Deschamps preside over his 80th game in charge of his country and become the longest-serving coach in the history of the French national team.
Uruguay eliminated European champions Portugal courtesy of an Edinson Cavani double.
The South American side took the lead within ten minutes when Cavani converted a Luis Suarez cross.
Early into the second half, Portugal replied when an unmarked Pepe thumped home a low header to equalise.
But the Portuguese resurgence was to be short-lived.
Minutes later, Cavani produced an unbelievable finish from the edge of the 18-yard line, as he curled the ball into the far corner of Rui Patricio's net.
The PSG frontman was replaced shortly after and looked to be in some discomfort as his side held on for the win.
Uruguay progress to the quarter-finals where they meet France on Friday.
