Wenger considers Gervinho's pace and movement to be a real threat to opposing teams and is delighted with the 25-year-old's improved finishing.
"The thinking was to use well his quality of movement and his pace," Wenger said. "But of course you have to overcome a little bit of an obstacle that he doesn't correspond well to the traditional image you have of a central striker.
"I did that [changed position] with Robin van Persie. He was more a technical player, it was not obvious to put him as the central striker.
"I did it with Thierry Henry, I did it now with Gervinho and I think I will do it as well with Walcott.
"They have other qualities that is well suited to our game. Our game is based on movement and technical ability and they have that."
