Lyon have warned those clubs interested in Moussa Dembele that the striker is not going anywhere.
The former Celtic forward, who has scored 10 times in 18 Ligue 1 appearances this season, has been linked with a move to the Premier League this month, with Chelsea particularly keen.
Manchester United are also reported to be interested but Lyon, who signed Dembele in 2018, said in a statement they were determined to keep hold of the 23-year-old.
"Olympique Lyonnais have taken note of certain information relayed by the media suggesting that Moussa Dembele could interest other clubs during this transfer window," the statement read.
"OL would like to reaffirm their desire, as they did in summer 2019, to keep Moussa Dembele.
"The club have full confidence in Moussa and are relying in particular on him to build a successful team for the seasons to come."
