Paris Saint-Germain had Kylian Mbappe to thank as his brace saw the runaway Ligue 1 leaders come from behind to win 2-1 at struggling Caen on Saturday in their final outing before their Champions League last 16, second leg against Manchester United.

A week after reaching a half-century of goals in France's top flight at the age of 20, Mbappe netted a penalty for the first time in his Ligue 1 career just before the hour mark.
