PARIS, Oct 8, 2018 (News Wires) - World Cup winner Kylian Mbappe scored four goals in 14 second-half minutes to lead Paris St Germain to a 5-0 win over Olympique Lyonnais in a bruising Ligue 1 encounter. Leaders PSG, already eight points clear of Lille, extended their winning start to the league season to nine games but it was a hugely flattering score for them after a match where both teams finished the first half with 10 men. Lyonnais, who had to substitute two players before halftime because of injury, more than held their own for the first hour and hit the post with the score at 1-0. Brazilian Neymar converted a penalty to give PSG a ninth-minute lead but the game took a dramatic turn when the hosts had Presnel Kimpembe sent off in the 32nd minute for a dangerous studs-up tackle on Tanguy Ndombele.
