PSG win their first home match of the season 5-2. Mbappe made up for his missed penalty after his low-driven cross was turned into his net by Sacko.
The defender then handled the ball in the box, allowing Neymar to slot it home to make it 2-0 before half-time.
The Brazilian made it 3-0 quickly in the second period as he headed home a deflected cross from Hakimi.
