Guinea

Les Bleus made it two wins from two thanks to the right-back's header, though they rode their luck against a spirited Guinea side, who had two first-half goals disallowed.

Amadou Diawara forced Guillaume Restes into a superb fingertip save just minutes into the tie before Jean-Philippe Mateta wasted a hat-trick of chances to put the hosts ahead.

A cheeky backheel dribbled wide, and a thumping header missed the target on either side of Soumaila Sylla's smothering save.

Naby Keita clinically picked out the bottom corner from an offside position just before half-time, with Abdoulaye Toure also seeing a goal ruled out moments later after meeting a free-kick.

France came to life in the second half and gave a warning sign when Loic Bade struck the post from a tight angle.

In the end, Sildillia proved the difference as he was left unmarked to meet Michael Olise's cross, and Sylla could not get to his thumping header.

France are through to the next round, and top Group A with six points, while Guinea sit bottom of the group having lost both of their matches so far.

Data Debrief: Les Bleus leave it late

For much of the first half in this game, France were sluggish and could have easily gone into half-time 2-0 down if it was not for two tight offside calls. 

In the end, Thierry Henry's side showed their quality, with Olise proving the key man. He created six chances, more than anyone else on the pitch, with one of those resulting in an assist.

It is the first time France have reached the quarter-finals at the Olympics since 1996, as they looked to end a 40-year wait for a gold medal in the event.

Thierry Henry's side remain the only side in the tournament to win all of their games so far, and made light work of their opponents on Tuesday. 

Jean-Philippe Mateta, who captained the side with Alexandre Lacazette on the bench, started off the scoring after the ball bundled its way into his path before finishing beyond Alex Paulsen in the 19th minute. 

In a game that saw Les Bleus accumulate 34 shots at the Orange Velodrome, their dominance was rewarded with two quickfire goals late on. 

Desire Doue would double the hosts' advantage from close range, with Arnaud Kalimuendo rounding off the scoring three minutes later to see France remain perfect. 

France's triumph saw them win their first three games at the Games for the first time in their history, while also keeping three clean sheets on the spin for the first time at the Olympics. 

In the other Group A encounter, the United States qualified for the knockout stages of the tournament for the first time since 2000 as they eased to a 3-0 win over Guinea.

A rampant start to the encounter saw Djordje Mihailovic and Kevin Paredes have Marko Mitrovic's two goals to the good just after the half-hour mark. 

Despite finishing the encounter with just 37.8% possession, the United States were clinical in the final third as Paredes put the game beyond doubt in the 75th minute. 

They return to action this Friday when they face Group B winners Morocco, who clinched top spot with a 3-0 win over Iraq while also finishing ahead of Argentina.
