Paris Saint-Germain returned to winning ways against AC Milan after the thumping they received against Newcastle.
Kylian Mbappe netted in the first half following a determined Warren Zaire-Emery solo run.
The 17-year-old fought off plenty of pressure in midfield before finding Mbappe on the edge of the box with a forward pass. The Frenchman chopped inside on his favoured right foot before fizzing a low shot beyond the motionless Mike Maignan.
