Neymar's two goals were not enough as Monaco punished sloppy defending to draw 3-3 at French league leader Paris Saint-Germain on Sunday.
PSG moved five points ahead of second-place Marseille, with PSG playing their game in hand at Monaco on Wednesday.
Robert Moreno's first league game in charge of Monaco, after replacing the fired Leonardo Jardim, was an impressive one as his side twice came from behind and nearly won late on at Parc des Princes.
Neymar put PSG ahead in the third minute with an excellent finish, controlling a clever lofted pass over the defense from Italy midfielder Marco Verratti on his chest and nonchalantly guiding the ball inside the near post.
But Monaco midfielder Cesc Fabregas picked out Wissam Ben Yedder with a flicked pass from the edge of the area and, after Ben Yedder was bundled over by goalkeeper Keylor Navas, midfielder Gelson Martins poked in the loose ball after seven minutes.
Monaco's second goal in the 12th looked alarmingly easy.
A team move started from the edge of Monaco's penalty area ended with Ben Yedder collecting a pass inside PSG's area, shuffling past a defender, and expertly beating Navas with a curling shot for his league-leading 14th goal of the season.
Eighth-place Monaco should have been 3-1 up but, with time to pick his spot, forward Keita Baldé placed his shot too close to Navas.
PSG punished that immediately, with Neymar collecting a pass from Angel Di Maria and curling a shot which deflected off defender Fodé Ballo-Toure for an own-goal in the 24th, making it 2-2.
After Monaco center half Kamil Glik hit the post with a header from a corner, PSG went ahead in the 42nd. Martins fouled Kylian Mbappé for a penalty, and Neymar sent goalkeeper Benjamin Lecomte the wrong way with ease for his 10th league goal.
Still, Monaco pressed forward and Russia midfielder Aleksandr Golovin curled wide with the goal at his mercy seconds before the break.
Lecomte reacted well to keep out Neymar’s shot early on in an even second half.
Substitute Islam Slimani punished more slack PSG defending to equalize in the 70th, turning home a loose ball after Martins bamboozled the PSG defense and his shot was deflected by Marquinhos into the alert Slimani’s path.
The referee disallowed the goal for offside, but then awarded it after a video review because Marquinhos’ intervention effectively played Slimani back onside.
Navas made a sharp one-handed save to keep out Slimani’s close-range header from a corner in the 88th. PSG was lucky to avoid a penalty since center half Thiago Silva deflected Slimani's header with his raised hand.
CLINICAL NANTES
Mehdi Abeid and Ludovic Blas provided the goals as Nantes won 2-0 at struggling Saint-Etienne to move up to fourth place.
Abeid put Nantes ahead in the 23rd minute with a powerful strike from outside the penalty area after Saint-Etienne's defense failed to clear the ball properly.
Blas netted three minutes after the break from Nigeria forward Moses Simon's pass.
Saint-Etienne's form has dropped in recent games and a ninth defeat of the season pushed coach Claude Puel's side down to 15th spot.
HOME COMFORT
Dijon extended its unbeaten home run to eight league games with a 1-0 win against Lille, despite having a player sent off early on.
Defender Hamza Mendyl received a red card in the 21st minute for kicking Luiz Araujo in the ribs.
After Lille missed several chances, Dijon scored in the 47th when Julio Tavares latched onto midfielder Mama Baldé's chested pass and shot confidently past goalkeeper Mike Maignan for his fourth league goal this season.
Both teams finished with 10 men after Lille midfielder Boubakary Soumaré was sent off in the 67th.
Lille dropped to fifth place behind Nantes while Dijon, which beat PSG at home this season, rose to 16th place.
