The highly-rated midfielder has recently been strongly linked with a move to Premier League side Arsenal.
Anigo told RMC: “It’s been six years since Mathieu Valbuena joined the club. If Arsenal wants to buy him, the discussion can be opened.
“When a player has spent five or six years at a club, out of respect for him, nothing is closed. We are very pleased with him, but if a big club is interested in Mathieu, people listen.”
