The Gunners recovered from an early goal to record a 3-1 win over their London rivals, but Wenger has moved to praise the performances of his two goalscorers.
"It is a pleasure to watch him [Cazorla]. It's a delight to see what he does on the pitch. I hope every young football player in England watches him," he told ESPN.
"He [Walcott] has that in him, but before, one or two years ago, when he went in front of the goalkeeper he would not always finish well, but now we are convinced he will score.
"We started [the season] with many questions about us, but of course we need to build up belief and convince people around us we have a chance. Apart from the Chelsea game we have been convincing and we have belief we can do something special."
The result has moved Arsenal into fifth in the Premier League table.
