I don't think he wants 400k from City. He might from Arsenal, he might see that as compensation for staying and playing in the EL which could result in him losing sponsorship money from not being in the CL - I don know
I think it's more likely he will play for City than Arsenal next season. But there is no chance he will be getting 400k a week basic wage from City
Think that's pretty much it – he is possibly demanding £400k + off Arsenal, simply because he knows they won't pay it – thus forcing his transfer to us, who of course, won't be paying him anywhere near that amount a week.
