From what I heard, Ozil wanted some assurance that the pay cut would guarantee no job losses.
And they've made cuts anyway so as much as I think it's obscene how much footballers get at the best of time, especially when they weren't doing their jobs, I don't think he is entirely to blame here (as much as I slated him at the time).
Oh who knows what's going on but it does feel like the whole thing has been very badly mismanaged by Arsenal. A colleague speculated to me that Ozil has mental health issues. Possible. I guess in time we'll get various people's accounts and try and piece it together.
