Lyon chief Jean-Michel Aulas has again confirmed that Arsenal have made an official approach to sign striker Alexandre Lacazette.
The 26-year-old is together with Kylian Mbappe at the top of Arsene Wenger's priority list for the summer.
But the Gunners are yet to meet the fee Aulas wants for the impressive Frenchman.
"I do not intend to cede Alexandre [Lacazette] quickly, because there is always the will of Atletico Madrid to bring it [the transfer] to January 1," he told L'Equipe.
"Now I also listen to what Alexandre says. I saw Arsene [Wenger] during the France versus England match.
"I was with Gerard Houllier and I understand that he told Gerard that there could be interest from Arsenal.
"But it's premature to say that things will happen. It takes a very large transfer before. A player of that quality cannot be allowed to leave without having his replacement.
"It will have to be at least that [£57m].
"Everyone knows that the offer of Atletico is €53m [£46.5m] plus €12M [£10.5m].
"As the leaders of Arsenal are well informed, they will be in those waters."
"The prices for a player who marks every year with between 25 and 30 goals, sometimes more than 30, is at least that.
"But frankly, I have not thought about Arsenal for the moment, because I thought that Alexandre would stay because of the failure, initially, with the Atletico Madrid move."
