Arsenal have been warned over the price of Montpellier striker Olivier Giroud.
Giroud has stated he'd like to join Arsenal next season.
But Montpellier chief Laurent Nicollin warned: "I keep reading that Olivier Giroud has a clause in his contract saying it is €10 million. It's not that simple.
"The fact that Olivier is now a French international involves changes in his clause, as does future selection or even a possible participation in Euro 2012.
"Today, the amount is over €16-20 million - and everything can change again."
