One of the Gunners' most turbulent summers in living memory saw them lose key players Cesc Fabregas, Samir Nasri and Gael Clichy to other clubs, with an 8-2 defeat at Manchester United adding extra embarrassment.
Wenger managed to salvage something with a flurry of deadline-day signings, though, and will task his new players with restoring the club's title credentials.
He admits, however, that the past weeks have been a struggle.
"In my job, you expect to suffer. So that's why when I go to hell one day, it will be less painful for me than you, because I'm used to suffering," he told a number of national newspapers.
"I could write a book about the summer. It was the most disturbed we have had since I have been here.
"The book would be quite an interesting read. Not because of me, but because of all that happened. It was unbelievable."
