For the first time this season, Ozil started in attack with Alexis Sanchez and Alexandre Lacazette at Goodison Park.
And all three were on the scoresheet as Arsenal bounced back from last week’s disappointing defeat to Watford.
Ozil has been criticised this season over his underwhelming displays.
But following victory at Everton, Wenger gave his backing to the Germany playmaker.
When asked if Ozil was back to his best, Wenger said: “I would say yes.
“I told him after the game that a fit Ozil is completely different. If you’re not 100% at your best, no matter how good you are, you are at a handicap.”
Wenger added: ”We should have been 2-0 or 3-0 up, but we were 1-0 down. We didn’t panic and maintained our focus. Once we equalised, it was all us for the rest of the game.
“I was [concerned] because recently we’ve been punished for every mistake we make away from home. But I knew there was a long time to go.
“Our away performances this season have not been rewarded.”
