Lyon boss Hubert Fournier has told RMC the club will not let reported Liverpool target Alexandre Lacazette leave the club in January.
Lacazette, 23, took his goal-scoring tally to a league-high 17 with a brace in Lyon's 5-0 demolition of Bordeaux on Sunday.
The France international has already beaten his previous best total for an entire season, which stood at the 15 he registered last term, and has been mooted as a potential solution to Liverpool's goal-scoring problems in the wake of Luis Suarez's departure and Daniel Sturridge's injury-enforced absence.
However, Lacazette signed a two-year contract extension at the Stade de Gerland in September, tying him to the seven-time French champions until 2018.
Following his team's win at Bordeaux, which lifted Lyon ahead of Paris Saint-Germain and into second place in the Ligue 1 table, OL boss Hubert Fournier revealed club president Jean-Michel Aulas had told him Lacazette is not for sale.
"I'm not the best person to speak about it. If it was only up to me, of course I would like him to stay," Fournier, who took over from former Arsenal midfielder Remi Garde in the summer, explained.
"But the president has rather reassured me, and above all, I don't get the impression Alexandre wants to leave during the January transfer window."
Having run into financial difficulties following the first decade of the millennium, Lyon changed tack and instead of snapping up the best talent Ligue 1 has to offer, Aulas has stated his intention to focus on bringing through the club's home-grown talents, including Lacazette, Clement Grenier and Nabil Fekir.
