The Gunners has sold Emmanuel Adebayor and Kolo Toure and have only signed Thomas Vermaelen this summer.
“I am very optimistic about the season and I am very positive about this team,” Wenger told the club’s official website.
“We always have to listen to peoples’ opinions, but you also have to trust what you see in the games and in training.
“Overall it was very positive preparation, and I believe we have shown quality in every game.
“It is unfortunate that now everybody goes away on international games, which is why we have to cross our fingers that everybody comes back in good shape.
“But overall, physically, everybody is ready to start.”
