Ozil's new contract is reportedly worth £350,000-a-week, shattering Arsenal's previous highest deal, and Wenger has called on the Germany global to back up his contract by taking a leadership role on the pitch.
The Germany playmaker has penned a three-and-a-half-year deal which ties him to the Gunners until June 2021. BBC Sport's David Ornstein had already revealed the lucrative terms of the new deal, including his wages of £350,000 per week.
The 29-year-old tweeted a photo of him autographing pictures, along with the caption: "Had a busy day signing things".
Attack: All eyes will be on Wenger to see if he'll hand record signing Pierre-Emerick Aubameyang his debut but I think he'll ease the Gabon global in to action from the bench.
With 46 assists coming in the Premier League, from 456 chances created, no other player in the league has been more creative than Ozil since the German signed for Arsenal.More news: Ben Simmons, Jaylen Brown send cryptic tweets after another All-Star snub

Ozil's contract had been due to expire at the end of the season.
Arsenal boss Arsene Wenger hopes Aubameyang's arrival will off-set the loss of Alexis Sanchez to Manchester United and the Gabon worldwide is determined to make a good first impression on the Premier League.
Ozil joined Arsenal from Real Madrid in 2013 for a then club-record of about 42.5 million pounds. "Once a Gunner, always a Gunner!"
Arsenal manager Arsene Wenger says new signing Pierre-Emerick Aubameyang has been ill and that his fitness will be assessed ahead of Saturday's match against Everton at the Emirates.
Earlier in the January transfer window, Alexis Sanchez left Arsenal to join Man United.
"Many predicted he (Ozil) wouldn't commit and not sign".
