Maybe, but it wouldn't surprise me if he has a behind the scenes agreement with Wenger and the club. I think I see a difference between Ozil's attitude and Sanchez's, but it may just be my hopeful imagination.
I can also see this as a possible scenario to secure a huge pay-rise should he sign on. How desperate are we to grab his signature and pay for that privilege.
Out of the two, Sanchez has a wider pool of teams interested in him than Ozil. That's why Sanchez has that laissez faire attitude.
