Download Guingamp 1 – 3 PSG (Ligue 1) Highlights Mp4
Guingamp opened the scoring on 20 minutes through Nolan Roux and thought they had doubled their lead through Nicolas Benezet five minutes later.
But after four long minutes waiting on a VAR decision, he was accused of tripping the PSG defender in the build-up to the goal.
Neymar salvaged an equaliser from the spot eight minutes into the second half before Mbappe used his strikers instincts to find space in the box before slotting past the keeper.
The 19-year-old then used his blistering pace to break through and delicately lob the keeper to kill off the game.
