France coach Didier Deschamps described the whistling of Olivier Giroud during his side's friendly win over Cameroon as "unfair".
The Arsenal striker was on the scoresheet as the Euro 2016 hosts claimed a 3-2 victory in Nantes on Monday.
"You hear what you want. The whistles were unfair tonight, but in Biarritz, he was applauded. People can be conditioned," he said.
"But Olivier scored again. When you say it, you are not helpful. You are free to say what you want but this is not necessarily the truth."
"It's been three weeks since he played," he said.
"This game was good for him, to get back into the pace. He can do better, but every time he touches the ball, there is something happening. And he has the quality of set-pieces, free-kicks, corners and it is something important.
"He is very important."
