The Gunners made it four wins in a row on Wednesday night when comfortably beating FC Basel 2-0 in the Champions League.
The result extended the North London side's unbeaten streak to eight matches in all competitions and these are the reasons Wenger feels that positive results are becoming a habit, particularly at the Emirates Stadium.
"It's down to hard work of course, but also belief and belief comes with the last results," Wenger said at his post-match press conference thanks to Arsenal.com.
"The confidence comes with the last result (3-0 home win over Chelsea).
"We were a bit edgy at home for a few games but now it looks like we are playing with full pace and power.
"Now it's down to us to continue to improve. I think we can do better and that will be down to our humility.
"We'll start again tomorrow morning and then focus on our next game (against Burnley on Sunday)."
