Lyon have suggested a big offer could lead to Jeremy Toulalan's sale after the midfielder was linked with Bayern Munich.
Reports have claimed that Bayern are considering a summer swoop for the France international, who has spent three years at Lyon.
The French champions' special advisor Bernard Lacombe is aware of Bayern scouts visiting Stade Gerland, but is unsure if Toulalan is the target.
However, Lacombe believes the sale of players in the past shows the club would be willing to let Toulalan go for the right price.
"Bayern scouts? They are here every match," Lacombe told Aujourd'hui Sport. "However, I don't know if they come for Jeremy.
"In the past, we had other players in the same position we wanted to keep, like Michael Essien and Mahamadou Diarra, and they finally left.
"At 40million euros (£37million), we will talk."
