There are many ways to inspire a team. You certainly won't see him running up and down the touchline bellowing instructions like a fucking nutter, but if he's picked up enough knowledge from Guardiola, he can inspire them in the training ground and instill confidence in them, so there is no need for him to shout on matchdays.
And at least he certainly gets the club and what the expectations are.
I'm not saying we should go for him, by the way, just that it's not as completely bonkers an idea as it may sound at first.
Let's not forget that we had a Guardiola disciple in Martinez. That worked out great.
