Neymar converted a penalty in each half but Paris Saint-Germain collapsed to a sensational 3-2 defeat at relegation-threatened Lorient in Ligue 1
Mauricio Pochettino's first loss as head coach means PSG missed out on the chance to return to the top of Ligue 1 in place of Lyon after sub Terem Moffi broke clear to net a stoppage-time winner.
Lorient were the better team before half-time and led through Laurent Abergel's first goal in almost a year
However, a tale of woe then unfolded for Houboulang Mendes, who conceded 45th and 58th-minute penalties, from which Neymar made no mistake.
Yoane Wissa replaced the embattled right wing-back soon afterwards and levelled with a fine solo effort before fellow sub Moffi snatched glory.
