AFP, PARIS: Neymar scored a second-half penalty as four-time defending champions Paris Saint-Germain toiled before overcoming 10-man Amiens 2-0 to reach the semi-finals of the French League Cup on Wednesday.

PSG were again without leading scorer Edinson Cavani, who also missed Sunday's French Cup rout of Rennes after returning late from his Christmas and New Year break in Uruguay.

Amiens' hopes of springing an upset were heavily undermined by the dismissal of goalkeeper Regis Gurtner on 34 minutes for a foul on Kylian Mbappe after charging out of his area.

And Neymar eventually made the visitors' numerical advantage count by winning and converting a spot-kick eight minutes into the second half at the Stade de la Licorne.

Mbappe, earlier denied by a fingertip save from Jean-Christophe Bouet, was then thwarted by a combination of the substitute keeper and the crossbar before firing another effort narrowly wide.
