The France international has been one of the standout performers in Ligue 1 this season and leads the goalscoring charts with 17 in 19 appearances.
Lacazette's latest impressive showing came in Sunday's 5-0 mauling of Bordeaux, with the striker starting and finishing the scoring in the rout at Stade Jacques Chaban-Delmas.
His goals have helped Hubert Fournier's men to second in the table ahead of the mid-season break and they will resume in the new year just two points behind leaders Marseille.
The 23-year-old insists there is no time for him and Lyon to pat themselves on the back, though, and wants a continued push in 2015.
"I must aim even higher," Lacazette told Lyon's official website. "I must also not forget the work of my team-mates.
"We know we have quality. We can do well. We must not stop here, we can go even higher."
Lyon have won four straight Ligue 1 matches and return to action against Lens on January 4 in the Coupe de la Ligue.
