I was the previous U21 Manager of my country. I know how it works in my place. When a manager does a great job, everybody (well, not everybody but a big number of managers) trust him the responsibility.
That's what happened in this last elections. We discussed that in the Forum, he was the best candidate, so the others just retired. That's why at the end he was the only one, no more candidates.
I mean, this manager did a great job with our NT. We we're sure he was gonna do it again, so we trusted him. In fact, our team was really close to the World Championship, we did the Repechage, but we lost it due to a lack of confidence I would say.
Anyway, it looks weird, but there were other candidates. But no one of these "other candidates" could assume the responsability as this one.
