The German displayed a nervousness allayed with sheer focus, the kind of sense you get from looking at a picture of Albert Einstein at work...
The relaxed smiles that were designed to win over the media were replaced with frank assessments of how Klopp 'is not interested' in how many journalists turn up to hear him speak.
He was edgier and more nervous. But, at the same time, you could see just how focused he was.
Every word the German uttered looked half-hearted - not in a bad way but because the other half of his brain looked as though it was still thinking about tactics, training and who to play in what position.
It was like looking at a picture of Albert Einstein at work. Every smile had a sense of 'I'd much rather you left the room and I carried on with my sums.'
This should all excite Liverpool fans. Things could well go wrong but Klopp is already giving off an air of what a workaholic he is. And, when you're a workaholic, you significantly reduce the chances of anything going wrong...
Perhaps one concern for supporters could be the fact the German keeps mentioning the paparazzi. He follows it up every time with the words 'but it's not a problem.' It clearly is, though, otherwise Klopp wouldn't mention it at least three times!
Overall, however, this was a different 48-year-old coach to the one who greeted life at Anfield with a joke and a wave. This is Klopp in his element, already fully focused. Hopefully, ready to deliver.
