Tbh we don't even know from which side the news of wanting the money comes. It could very easily come from Arsenal's side too, as reasoning why Alexis didn't commit to a new contract. Given how many fans would rather see him gone, it does also seem to work.
In general it's rather hard to tell right now anyway as we don't even have much information on the other players either. There's not been a lot of talk about Özil signing a new contract, despite being back with the team and having more team to think about his future, so there might really be more to this whole topic than we actually know.
