Paris Saint-Germain overcame an injury to Kylian Mbappe as goals from Fabian Ruiz, Lionel Messi and 16-year-old Warren Zaire Emery saw them beat Montpellier 3-1 in Ligue 1 at the Parc-des Princes on Wednesday.

Mbappe had already missed a penalty, and its subsequent retake for a Montpellier encroachment, before coming off in the 21st minute with a worrying-looking injury, clutching his hamstring as he went straight down the tunnel.

But after Messi and Achraf Hakimi both saw goals chalked off for offside, Fabian poked home in the 55th minute before Messi added a second to put Christophe Galtier's men in control.

Arnaud Nordin pulled one back only for Zaire Emery to come off the bench to score his first senior goal, sealing a victory that is PSG's first in three league games and puts their hopes of lifting a ninth title in 11 seasons back on track.

PSG were awarded a penalty after just seven minutes when Christopher Jullien hauled down Sergio Ramos from a free-kick into Montpellier's box.

Mbappe's initial spot-kick was saved by Benjamin Lecomte, but a Montpellier encroachment prompted a retake, only for the France international to see his second attempt tipped onto the post by Lecomte before sending the rebound over the bar.

After Mbappe and Sergio Ramos (head) were both forced off with injury, Messi thought he had put PSG in front with a clever chipped finish, though a VAR review ruled him offside to send the game into the break goalless.

Messi blasted into the side-netting following half-time before Hakimi saw a wonderful strike from distance ruled out, again for offside in the build-up.

But PSG's wait to break the deadlock ended shortly after, Hugo Ekitike nodding across for Fabian to stab home from close-range.

Messi added a second with 18 minutes to play as he coolly dinked into the bottom corner from Fabian's perfectly weighted throughball, though Nordin caused some anxiety for the visitors by finding the bottom corner in the 89th minute.

Substitute Zaire Emery ended any hopes of a Montpellier comeback though by blasting home a third in the dying seconds.

Luciano Spalletti was delighted to have quietened Napoli's critics after Fabian Ruiz's 94th-minute strike saw off Lazio at the Stadio Olimpico and propelled the visitors to the Serie A summit.

After Lorenzo Insigne had opened the scoring, Pedro's superb late volley looked to have denied Napoli a crucial victory, only for Fabian to curl in a brilliant last-gasp winner to put Spalletti's men ahead in an enthralling title race.

Napoli's return of 18 points from their eight league matches in 2022 is the best in Serie A, as they bid for a first Scudetto since the Diego Maradona era, while the late goal condemned Lazio to just their second home defeat of the league campaign.

Spalletti, who joined in with his players' wild celebrations after the goal, said after the contest Napoli deserved the victory, but he seemed more concerned with quietening those who have criticised his men.

"I think overall the team deserved the victory," he told DAZN.

"I want to underline that everyone keeps moaning that this team doesn't have character, it's soft, it's sluggish; I want to hear them say that now.

"This team definitely has character. We lost to Barcelona [4-2 in Naples] after getting a result at Camp Nou, it was my fault because I told them to take that approach.

"I see an ugly atmosphere around this team, people trying to say we lack character. I want to see them say that now.

"We got knocked down, we got straight back on our feet again and poured forward to find the winner. I don’t think it's a bad thing to say this was a deserved victory." 

Fabian has now scored the most goals from outside the box in this Serie A this season, with all six of his strikes coming from range. Moreover, the midfielder has now netted as many goals this term as he did in the 2019-20 and the 2020-21 campaigns combined.
