France coach Laurent Blanc has told Real Madrid there's more to come from striker Karim Benzema.
Benzema struck an impressive hat-trick in their Champions League victory over Auxerre.
Blanc told L'Equipe: "He has not yet confirmed his potential, but he is a gem. Looking at his statistics, he has a great advantage over others in his position, and he has talent.
"I will experience all methods for Benzema to exploit his potential."
Blanc, however, warned: "If it is confirmed that that situation in terms of minutes on the pitch does not improve, it will become a big problem, but it is hard to leave Real Madrid, who are one of the best clubs in the world."
