Metz 1-5 PSG
All over.
Leaders PSG trounce bottom side Metz.
Metz 1-5 PSG
One minute off added time...
Metz 1-5 PSG
Remember, the score was 1-1 when that Benoit Assou-Ekotto sending off on 55 minutes took place.
It has not been a 5-1 game, to be honest.
Lucas Moura

Neymar involved again, clipping a sublime ball to the back post for Thomas Meunier.
The big Belgian plays it across first time towards Lucas Moura, who makes a hash of the initial effort, mis-cueing it onto the post.
But it bounces nicely back to him to tuck home from close range.
Metz 1-4 PSG
Oh my.
Neymar with a naughty drag-back pass into the path of Kylian Mbappe, but the youngster cannot sort out his feet and Metz can clear.

Last change for PSG.
Christopher Nkunku on for Adrien Rabiot.

10 minutes remaining. PSG playing out time now.
Metz 1-4 PSG
RIP MSN.
It is all about MNC now.
Mbappe, Neymar and Cavani all on the scoresheet for PSG in their first start together.
Metz 1-4 PSG
When you've got this luxury...
Two goalscorer Edinson Cavani comes off and Lucas Moura enters the action.
Thiago Motta also makes way for Giovani Lo Celso.
Edinson Cavani
This is getting better and better and better for PSG.
It is messy, but they all count.
The man Yuri Berchiche puts a low cross into the box which Moussa Niakhate fails to clear.
It falls nicely into the path of Edinson Cavani, who dribbles a finish past Eiji Kawashima.
A few more coming to add to PSG's goal difference?
Metz 1-3 PSG
Four goals in four games now for Neymar. How many can he get this season?
Metz 1-3 PSG
One assist to his name, Adrien Rabiot looking to score himself now but blazes a shot over the bar.
Neymar
All over?
Beautifully done by Neymar.
The world's most expensive player turns around 30 yards out and advances to the edge of the area before curling a low shot into the net.
The Metz defenders could not get a hand on him.
PSG can get a few more tonight. Still 22 minutes remaining.
Metz 1-2 PSG
Former Cheltenham man Yuri Berchiche looking to get a goal on his full debut for PSG, but his low drive is straight at Eiji Kawashima.
Metz 1-2 PSG
Is it over the line?? No says the ref. A matter of inches.
Edinson Cavani lets the ball drop in the box and hammers an absolutely thumping shot which cracks the crossbar and falls down onto the line.
The whole ball did not cross.

Louis Porter: Well, the answer to the debut goalscorer question earlier has now changed because of Mbappe.
Metz 1-2 PSG
By the way, in the aftermath of that goal, Metz boss Philippe Hinschberger was furious and walk a few yards onto the pitch to confront the referee.
Presumably, for the harsh red card given to Benoit Assou-Ekotto.
Anyway, the ref is not having any of it and Hinschberger to the stands for the rest of the game.
Metz 1-2 PSG
Ooh, nearly a quick-fire second for Kylian Mbappe.
The Frenchman is found by Neymar and stretches out his foot with a shot towards goal, but Moussa Niakhate is on the line to flick the ball away.
Edinson Cavani then attempts an acrobatic effort, but it sails wide of goal.
Kylian Mbappe
Had to be him.
A debut goal for Kylian Mbappe.
He chips a ball into the box which Ivan Balliu clears straight back to the young Frenchman.
Cool as you like, the would-be £165.7m man drills a right-footed shot low into the bottom of the net.
Brilliant. Eiji Kawashima no chance.
