Of course we don't but the lad certainly seems to be knowledgeable and hard-working going by his coaching career so far. Yes, we need more than those two traits if we're to become successful again but as much we should be wary of any possible nepotism (or indeed cronyism), neither should certain associations automatically rule people out.
FWIW, I'd much rather have a more experienced new manager - one who has demonstrated they can win things on a regular basis - but Clement's CV reflected that to a degree and that went pear shaped rather quickly.
In any event I can't affect the outcome so I'm just hoping whoever we appoint hits the ground running.
