This might explain why he didn't click with the Greek NT. Fundamentally incompatible. For the Greek NT you either have to be a megalomaniac (Otto) or morose (Santos). We don't do happiness. Maybe the idea of working with a happy manager just freaked the players out. Fried some neurons to the point that the poor kids need therapy and can't beat a bunch of amateur fishermen.
N.B. I still wake up in cold sweats thinking "it was only a dream" and then realise ... oh ####, we actually DID lose to a bunch of fishermen.
Back on topic, what Liecester have done has been a sheer pleasure to behold. Smack those big boys down!
