Rafa is probably the best coach we have had in a long while. Even Igor Biscan and Traore did a decent job under him. He had other failings, but if we want just a coach and if Rafa is willing to work in that set-up ....then why not?
I don't think he will be approached. rafa would definately be more popular than the owners and when/if good results started they fear a power struggle and given rafa's past who's to say they wouldn't get one?
