Mbappe starred for PSG with a stunning goal and providing an assist as Unai Emery’s side secured their fifth straight win and sentenced Metz to their fifth Ligue 1 loss in the same number of games.
It was top against bottom clash at the Stade Saint-Symphorien. Metz had not grabbed a point from their opening four matches while the guests had won every one of the four. PSG figured out how to stretch out their ideal start to the Ligue 1 season with a triumph on the night of sensation Kylian Mbappe’s debut.
PSG’s lavishly amassed forward line gradually grew into the game and their first genuine chance came when Draxler strung the ball through to Cavani who dinked over the keeper but onto the post.
The breakthrough then came when Neymar’s prodding through ball was met by both Mbappe and Cavani, but it was the Uruguayan who assumed control of the ball and rounded the goalkeeper before slotting into the unfilled net to give his side a merited lead.
The 18-year-old – who will cost PSG 180m euros (£165.7m) when he influences his loan move from Monaco permanent next summer – inspired all through alongside the world’s most expensive player Neymar.
Mbappe’s confidence was unmistakably growing as he set Cavani up for two quickfire shots. The first chance was made by Mbappe with a dazzling back heel to the Uruguayan, who let go of a firing strike into the keepers’ hands from the edge of the box. The French international at that point sent a delightful cross into the box with the outside of his foot, and Cavani headed down, driving Kawashima into making a decent spare.
In any case, the home side plainly hadn’t perused Mbappe’s content as they leveled only 6 minutes in the wake of falling behind. Dossevi had a lot of space on the right side of the box and he crossed in for Riviere to head home from short range with his side’s initial shot on target.
But Metz were standing their ground at 1-1 until previous Tottenham left-back Benoit Assou-Ekotto was tentatively sent off for fouling Mbappe.
That was the defining moment as Mbappe at that point drilled home from 20 yards to put Unai Emery’s side back ahead.
Neymar, Edinson Cavani’s second of the game and a tap-in for substitute Lucas Moura added some gleam to the inevitable scoreline.
The annihilation leaves Metz without a point this season, while champions Monaco have the opportunity to draw level with PSG at the best when they travel to Nice on Saturday.
