I think this highlights to me the issue in international coaching regardless of who it is. Coaches at international level should have a shelf life, most of the issues all face is avoided when we have a limit of one or two WC cycles. The favorites thing isn't as much of an issue, and things are kept fresh; if the new guy isn't working, you can change him out the next cycle.

Southgate also highlighted this in football, where it holds back a team.

I know some might disagree, but international coaching has moved on, and it takes a special kind of coach to manage the turnover between cycles while being ruthless and still keeping a team's morale high. Its so rare, I would argue it is chasing a white rhino.
