Ousmane Dembele scored his second hat-trick of the week as Paris St-Germain won at Brest to move 13 points clear at the top of Ligue 1.
The France forward also registered three goals in PSG's Champions League victory over Stuttgart on Wednesday.
Dembele, 27, has now scored 14 goals in his past eight appearances, with his impressive return in front of goal carrying him top of the Ligue 1 scoring chart.
"Ousmane can become the player he wants to be. If he remains confident in front of goal, he has no equal," PSG manager Luis Enrique told beIN Sports.
"He can score in any position, even with his head. He's a phenomenal player."
PSG, who will face the same opponents in the play-off round of Europe's elite club competition in February, are looking for their fourth successive French title and 11th in 13 years.
They remain unbeaten domestically but were made to work hard for their victory in Brittany.
Romain del Castillo drew the hosts level after the break and Ludovic Ajorque also scored before two late Goncalo Ramos goals sealed PSG's win.
Marseille, who are second, host Lyon on Sunday (19:45 GMT).
