Watch: Neymar, Mbappe open PSG Champions League scoring accounts

Celtic will feel hard done by during Tuesday's Champions League encounter with Paris Saint-Germain after cries for a foul were immediately followed by groans in the stands when Neymar opened up the scoring.

The Scottish champion appeared to be due a free-kick when Scott Brown was taken down by a cynical challenge.

However, Celtic's cries fell on deaf ears as PSG raced up the pitch. Adrien Rabiot delivered a beautiful ball into the path of Neymar, who raced by his marker and produced an unstoppable finish beyond Craig Gordon.

Shortly after, PSG's other lucrative summer signing, Kylian Mbappe, doubled PSG's lead with a close-range strike. He becomes the first ever player to score a Champions League goal as a teenager for two different teams (PSG and AS Monaco).
