The night the bespectacled nerd in a grey suit and tie took on Der Kaiser of German football, Franz Beckenbauer, there would only be one winner – and it wasn't Manchester United manager Ralf Rangnick.
'Kopfmensch' was one of the more polite terms thrown at Rangnick that night, which translates literally a person full of head knowledge, the implication being that they lack emotional intelligence.
Geek might be the closest word in English. In fairness, he did look a little like an art critic on Melvyn Bragg's South Bank Show, never a good look when trying to win over the football establishment.
