I hate that this situation exists and I don't really understand it. I guess it all makes sense if Arteta is a total dickhead who would prefer to cut of his nose to spite his face, but it just seems too ridiculous to be true.
I mean, it also makes sense if Saliba is the one driving the whole thing, whether out of spite or simply preference, which I don't think is any more far-fetched considering the power players and agents have these days.
