Kylian Mbappe's return could not have come at a better time for Paris Saint-Germain.
The Ligue 1 champions got off to a good start last weekend when they beat Caen 3-0, but were in a spot of bother away at Guingamp tonight.
Nolax Roux put the hosts in front and Thomas Tuchel's side turned in a truly woeful first-half display.
Timothy Weah and Angel Di Maria really struggled in place of Mbappe and Edinson Cavani, while Neymar struggled without his usual two colleagues in the side.
Mbappe was brought on after half-time and reminded everyone why he really is one of the world's best players.
Neymar equalised from the penalty spot in the second half and then Mbappe struck, notching a brace to seal a priceless win for PSG.
And his second goal really was a thing of beauty. You can watch it below.

That touch, composure and that lovely dink over the goalkeeper, just wow. Every time you see him you just wonder how he is only 19-years-old.
And there was one moment during his 45-minute cameo that highlighted how complete of a footballer Mbappe is.
France's World Cup star beat two defenders effortlessly with close control and athleticism, before playing a perfect through ball to a teammate.
How on earth is anyone going to stop Mbappe this season?

He just keeps on showing up Neymar, doesn't he?
PSG handed Mbappe their famous number seven shirt before the season kicked off and he's already justifying that decision.
Prior to the match, Tuchel stated that he was not concerned by Mbappe's goal statistics, but was more focused on his development.
"He is 19 years old and an incredible talent," he told a pre-match news conference. "I do not expect from him in terms of how many goals, how many assists - more development personally.
"After his big success and the big role he played in the World Cup, now being here in the second year it is very important that we guide him on his way, keep him straightforward, calm him down when it's needed and push him when he's needed.
"That's more what I want from him in terms of development instead of this amount of goals or this amount of assists."
Think he's developing just fine, Thomas.
