Wenger believes Sanogo has plenty of raw potential, but says he must work extremely hard if he is to fulfil it.
“He is very, very ambitious and believes in his quality,” he said. “He is very passionate and naturally has a great desire. You can see that in games. He is ready for a fight.
“When you look at his stature, he is a similar shape to Giroud but you feel there is a lot more to come out with him. He has a lot of improving to do. But you have to be open-minded. If he does well, he will play. If he doesn’t, he won’t.
“I believe up front that it's not experience that decides things. At the back, it's different. But up front it's an instinctive job. Experience helps a little bit. But the belief, the confidence, is more important up front than the experience.
“When I started to play Anelka, everybody said: 'Why do you start Anelka, why not buy a striker?' We won a championship with him. It's just like that, if we feel they are ready then they play.”
