Lyon striker Alexandre Lacazette is not for sale, president Jean-Michel Aulas has insisted.
The 24-year-old French international is a target for West Ham United, Paris Saint-Germain and Arsenal according to recent reports but is expected to stay with the Ligue 1 side.
"For a sale to be made, all three parties must agree," Aulas told French daily Le Progres.
"We have refused several offers, the most important from West Ham for 40m euros and we refused it
"It is an answer that says I want to keep him, but I'm not sure because ultimately it is he who will decide.
"I do not want on August 28, ahead of the Champions League, to find ourselves in the same situation as Monaco [who sold Anthony Martial to Manchester United last summer]."
