Lyon boss Bruno Genesio has admitted that he could still lose Alexandre Lacazette this month but only if the French club receive an offer they cannot refuse.
Lacazette, 25, is in high demand after scoring 48 league goals to help Lyon finish runners-up in Ligue 1 in each of the past two seasons.
Arsenal have already had an offer of €35 million for Lacazette rejected and Lyon president Jean Michel-Aulas is confident that the Gunners will not return with another bid.
Aulas is also set to offer Lacazette a new contract to ward off interest from Arsenal and Paris Saint-Germain.
When RTL asked Genesio on Monday if his star striker could still leave the club before the close of the current transfer window, the Lyon boss said: "When you say 'could leave,' of course, every player who is sought after could leave, by definition, since, as my president has said, there are sometimes offers that cannot be refused.
"But in any case, my desire and my responsibility as manager is to ask that the best players in my squad stay at Lyon.
"That's the case with Alex -- he's the leader of my attack. He's a player that's very, very important for the team, as are others incidentally.
"For the moment, I've been assured by my president that we will keep these players, but in football and during the transfer window you always have to remain prudent with this type of statement because you never know what might happen between now and Aug. 31."
