(This is what I meant to say, apologies new here and don't know how to delete my first post!) Maybe this could be Begovic? Very experienced, just left QPR, undoubted quality and could looking for a coaching position in the near future(something in which we seem to do well with experienced pros). Celtic were allegedly sniffing around but that's gone cold. This btw is all just speculation.... just the immediate name that sprung to mind.
