"I've been to football clubs and other sports [clubs] before where they don't give a great deal away but he was wonderful," said Kearney of Klopp. "Sometimes the person you are talking to can be a bit reluctant to open up but I thought Jurgen was very open and I found that very, very enlightening to be fair."
Kearney was particularly interested in finding out about player development, which Klopp excelled in at Dortmund and is a particular strength of German football.
"I asked about the academy and the way they develop the players in Germany," said Kearney. "It is a lot different to the way it is here in England. It was a wonderful conversation, really enjoyable."
Klopp had seen bits of the Rugby World Cup but this was his first taste of the 13 man code.
"He knew a little bit about rugby," said Kearney. "He watched us train for a bit and saw the contact. He got a little bit of an appreciation for it and I think he is planning on watching the game on Saturday (Sunday NZT)."
Kearney also revealed himself to be a English Premier League fan, though he has developed a habit of switching teams over the years.
"I am a big soccer fan," said Kearney. "A couple of years ago I was riding Liverpool, last year on Chelsea, this year I might stick with Arsenal. Back in my teenage days I followed Spurs with Ossie Ardiles, Ray Clemence, [Glenn] Hoddle...so I have a bit of background in English football."
Melwood is a remarkable facility. It features three full size football grounds, including one that is made to the exact dimensions of Liverpool's Anfield ground (101m x 68m).
The pitches also feature full under soil heating, so they can be used throughout the harsh winter months in the north of England.
Melwod also boasts rehabilitation rooms, a gym, a swimming pool, a press meeting room and a restaurant.
The Kiwis enjoyed the experience, and even had an impromptu football session at the end of training. Martin Taupau revealed a wicked left foot shot - sending one strike over the top of towering perimeter fencing and onto another field while Roger Tuivasa-Sheck, Adam Blair and Kodi Nikorima impressed with their juggling skills.
The Kiwis have a day off tomorrow, before the captain's run at the DW stadium at Wigan on Friday (Saturday NZT) ahead of the game on Saturday (Sunday NZT).
