Kylian Mbappe scored and Gianluigi Donnarumma saved a penalty as Paris Saint-Germain surged eight points clear at the top of Ligue 1 on Sunday with a 2-0 victory over last season's runners-up Lens.
Bradley Barcola gave PSG the lead with his second goal for the French champions after Donnarumma had kept out an early spot-kick from Przemyslaw Frankowski at the Stade Bollaert.
Lens are a far cry from the team that finished a point behind PSG last term, but their home form remains strong and they had an 11-match unbeaten run snapped just before the winter break.
However their hopes of fighting back suffered a critical blow when Jonathan Gradit was sent off late in the first half following a VAR review for bringing down Barcola as the last defender.
