Paris-Saint Germain put a troublesome week behind them to register an emphatic 3-0 win over Nice in Ligue 1 on Sunday. France forward Kylian Mbappe marked his return to action with a fine performance as champions PSG ran out comfortable winners at the Allianz Riviera. Mbappe, who missed the opening three games after contracting the coronavirus, fired PSG ahead with a 38th-minute penalty and had a role to play in Angel Di Maria's strike before Marquinhos headed home the third in the second half. PSG had made a poor start to their Ligue 1 title defence, losing their first two matches and only managing a last-gasp 1-0 home win over Metz on Wednesday. This after Neymar was involved in a mass brawl, and was subsequently sent off, during the match against Marseille. Neymar was one of five players shown a red card at the end of PSG's loss in <em>le classique</em>, and later claimed Marseille defender <a href="https://www.thenational.ae/sport/football/neymar-handed-two-match-ban-as-ligue-1-opens-racism-investigation-after-psg-marseille-brawl-1.1078961">Alvaro Gonzalez had made racist remarks</a>. Mbappe blasted his spot-kick into the roof of the net after he was fouled by Khephren Thuram. Nice goalkeeper Waller Benitez could only parry the forward's low shot for Di Maria to sweep home the rebound on the stroke of half time as the visitors doubled their advantage. PSG missed a string of chances in the second half with Mauro Icardi hitting the post, before Marquinhos added the third with a glancing header from a Di Maria cross. The result lifted PSG to seventh place on six points from four games, with Nice slipping to 10th also on six points. PSG players wore jerseys with names written in Mandarin. PSG have done this previously to celebrate the Chinese New Year, but the club did not elaborate as to why they did it this time.
