Wenger was the subject of protests last season, and is already having his role at the club for this term questioned by fans following the disastrous 4-3 loss at the Emirates yesterday to rivals Liverpool.
That would rule him out of Arsenal's next two games, against Leicester on Saturday and Watford the following weekend before a possible return on September 10 against Southampton.
Iwobi scored twice in 13 appearances for the Gunners in his last season.

Arsene Wenger has been left reeling with the news that Aaron Ramsey is facing a month out with a hamstring injury. The midfielder was hoping to carry on his form from the Euros, which saw him being included in the team and he did impress in the first-half against Liverpool, before being replaced on the hour mark with the injury.
Laurent Koscielny is not match fit after returning to training just a week prior to the start of the season, and the manager will be wary of rushing him and risking another injury.
The double session will go some way to addressing that but will not fix the issues with long-term absentees Per Mertesacker and Gabriel.
"I pushed Ramsey in and he got injured", Wenger admitted after the game. Goals from Oxlade-Chamberlin and Calum Chambers were not enough for the gunners to come back into the game as Jurgen Klopp's side emerged victorious. The Valencia man was decent at Euro 2016 and most Arsenal fans would be happy if the 24-year-old joined the club in the coming weeks.
