Monaco reached the top of the Ligue 1 table after coming from behind to beat Angers 2-1 at the Stade Louis II.
The visitors made a strong start as Danijel Subasic was worked twice inside the opening 10 minutes.
Thomas Mangani's volley from inside the area was gathered by Monaco's stopper before Famara Diedhiou's stinging effort from a wide angle forced Subasic to tip the ball from under his crossbar.
Monaco responded well and Bernardo Silva saw a 20-yard effort gathered by Mathieu Michel while an unmarked Guido Carrillo should have done better with a header from Almamy Toure's delivery.
Half-time came without a breakthrough but just after the restart Angers thought they had opened the scoring when Diedhiou beat Subasic, but the linesman's flag cut short any celebrations.
However, Diedhiou had the ball in the back of the net just seconds later and this time his effort stood.
Toke Ekambi made the difference on the right and his delivery was seemingly handled into Diedhiou's path by Cheikh Ndoye, which left the Senegalese striker to poke home from close range.
Angers' lead lasted little more than 10 minutes, though, as the visiting defence failed to clear their lines and Kamil Glik was on hand to fire beyond Michel for the leveller.
And the turnaround was complete on 76 minutes when Dickson Nwakaeme inadvertently put through his own net after Michel had initially saved Glik's header.
The visitors should have levelled in added time when Ndoye did well to nod Mangani's delivery into the path of Ismael Traore but the Ivorian defender failed to find the target with his volley.
