PSG move to within a game of winning their first title in 19 years, but finish with nine men after two players, including David Beckham, get sent off.
Paris-Saint Germain were able to collect all three points away from home, however they must pay the price of reckless challenges, as two players were sent off late on.
Javier Pastore gave the future champions the only goal of the game on 50 minutes, however it was late on that the game was marred.
Marco Verratti was first sent off for his second bookable offence on 81 minutes, before David Beckham was given a straight red card after his late and reckless challenge deep into injury time.
