It was lights out at Celtic Park as the men from France did not show any love.

After spending stupendously during the summer transfer window, PSG on Tuesday night put themselves forward as genuine contenders for the UEFA Champions League title with a ruthless display away to Celtic.

Paris St Germain's attacking trio of Neymar, Kylian Mbappe and Edinson Cavani were all on the scoresheet as they tore Celtic apart to lead the French club to a 5-0 rout.

Speaking after the big, the world's most expensive player, Neymar said it was delight to have a flawless start to the Champions League.

"I'm very happy. It was a fantastic match and I'm happy for the team. It was an important win," Neymar told reporters.

Asked about Mbappe, he said: "It's always a pleasure to play with great players, even though he's young. For me, he's a great player and he has the potential to improve even more."

Cavani added: "We stayed focused throughout, not just when we were attacking but when we defended too. It was the perfect match, the match we had to play here to get the three points."

In the next round of games, PSG will host Bayern Munich in a mouthwatering clash on Sept. 27, while Celtic visit Anderlecht.
