Fontvieille, Monaco – Emmanuel Riviere tallied three goals to help Monaco cruise to a 4-1 home victory against Montpellier on Sunday.
The result continues a good start to life back in Ligue 1 for the big-spending newcomers, who opened the campaign with a 2-0 win at Bordeaux.
Summer-signing Radamel Falcao scored for the second time in as many games when he fired home a penalty kick after 18 minutes, with Lucas Ocampos drawing the penalty on Montpellier's Siaka Tiene.
The visitors answered six minutes later through Victor Montano, who headed home a cross from Benjamin Stambouli to level the match.
But Riviere took over from there, restoring Monaco's lead shortly before the break with a lobbed shot over goalkeeper Laurent Pionnier.
Riviere doubled his tally in the 57th when he redirected a corner kick from Yannick Carrasco past Pionnier, while Montpellier went down to 10 men following Daniel Congre's red card.
The man advantage allowed Riviere to complete his hat trick by scoring on the rebound from Carrasco's saved shot.
PSG was held to a second consecutive draw on Sunday as the defending champions needed a goal from Edinson Cavani in the 86th minute to salvage a 1-1 home draw against Ajaccio, leaving the club four points back of the leaders through two games.
The other match on Sunday saw Lorient come from a goal down against Nantes to snatch a 2-1 win, with the decisive goal coming in the 61st minute from Jeremie Aliadiere.
