Mbappe bent home a stunning opener before Giroud doubled France's advantage after 33 minutes, with the Milan striker moving to within three goals of his country's all-time goalscoring record with his composed finish.

Paris Saint-Germain star Mbappe won and converted a 76th-minute penalty and Ben Yedder poked home a fourth with nine minutes remaining.

South Africa finished the game with ten men after Khuliso Mudau's late dismissal, with Guendouzi joining the scoring late on as the world champions recorded a seventh consecutive win.

Giroud met Lucas Digne's fifth-minute cross with a firm header to force a strong save from Ronwen Williams, before Mbappe miscued a right-footed finish from 12 yards out after being picked out by the full-back.

But the PSG striker opened the scoring in spectacular fashion on 23 minutes, retrieving Antoine Griezmann's cross before bending a stunning strike into the top-right corner from the edge of the area.

Les Blues needed just 10 more minutes to double their lead, with Griezmann again turning provider when he fed Giroud, who rounded Williams to roll home his 48th international goal. 

Williams made strong near-post saves from both Giroud and Mbappe as France continued to dominate after the break, before the impressive Digne crashed a fine volley against the upright on the hour.

Mbappe marked a starring performance with another goal with a quarter of an hour remaining, drawing a foul from Siyanda Xulu with a terrific burst into the penalty area before rolling the spot-kick into the bottom-right corner.

There was still time for Ben Yedder to add some gloss to the scoreline when he prodded over the line from Paul Pogba's header, before Mudau capped a terrible night for South Africa by seeing red for an awful challenge on Adrien Rabiot.

But Les Blues were not done yet, adding a fifth when Guendouzi bent home his first international goal after latching onto Mbappe's pass.
