Ozil arrived in north London in the summer of 2013 from Spanish giants Real Madrid for a club-record fee of £40m.
The former Schalke ace struggled to adapt to the rigours of the Premier League in his first season-and-a-half at the Emirates and was often blamed for the team's failures on the pitch.
But he has turned things around in recent months to become a vital part of the Gunners' starting XI.
The Germany international, 27, is currently on a hot streak and has bagged 11 assists and three goals in 17 appearances this season.
Wenger has been impressed by the midfielder's recent displays and believes they are the result of the former Real star making more of an effort to get into the box.
“What is interesting about Mesut’s game is that he is not only a provider now, he likes to get on the end of the things,” Wenger said.
“What he has added to his game is the runs into the box.
"He played before like he was not too much obsessed [by goals] and more by providing, and I think he has a much better balance in his game now, giving, assisting and scoring.
“At the start, in the first season, there was a lot of scepticism around him. I think the quality of his performances have turned opinions. He now has the support of everybody who loves Arsenal.
“You look at the players who give our assists and you will see who does it. I think the best assist player at the moment is Ozil, but we have many providers.
"We have Alexis, Ramsey, Cazorla - they are all people who can create chances. You could see Campbell the other night has given a great assist to Alexis. I think all our players have technical ability to do that.”
