The experienced manager went onto state that Özil has vastly improved over the past year and praised his hard working attitude.
“It’s a big season for him [Özil] because he had a difficult start last year and in the second part of the season he was very important [for us],” Wenger was quoted as saying by Goal.
“He’s improved his defensive attitude, he works hard and offensively he’s a top-class player.
“There are many offensive players who have an important season in front of them but I’m confident because I think they have the quality.”
Özil joined Arsenal two summers ago from Real Madrid for a record £42.5 million transfer fee and finished last season n top form after a lengthy spell on the sidelines due to an injury.
The World Cup winner has won two Vitality Arsenal Player of the Month and a PFA Fans Player of the Month award since the turn of the year.
Özil provided nine assists and five goals in 32 appearances for Arsenal in all competitions last season.
The 26-year-old enjoyed a break in Los Angeles before returning to North London for the beginning of pre-season training.
