White and Havertz scored braces to batter their London rivals 5-0
Ozil has been under the spotlight following anonymous performances in recent defeats to Watford and Chelsea and did little to deflect the criticism after missing a host of chances in Arsenal's 2-0 Premier League win over Hull City on Saturday.
The 28-year-old Ozil, who has often divided opinion among supporters since his club-record move from Real Madrid in 2013, has been on the periphery of games in recent weeks and has not scored in his last eight matches.
"I felt he did not feel confident (against Hull)," Wenger added. "It's always a problem because you think he can deliver something special, but it's true that technically he missed things that he is not used to."
