A one-time colleague of Jurgen Klopp has described him as "crazy" and "egocentric", but also "special".
Former Borussia Dortmund physiotherapist Frank Zollner says Liverpool boss Jurgen Klopp can be really "crazy" and "egocentric", but also labelled him as a "special" person.
Zollner was at the Bundesliga club Dortmund for 17 years and worked alongside Klopp at the Signal Iduna Park.
The German coach guided the Merseyside club to a sixth Champions League triumph in June 2019 and before the coronavirus crisis he was on the verge of landing Liverpool's first championship since 1990.
Speaking to Goal and SPOX about Klopp, Zollner said: "He's a special guy. There were so many days when you'd think: 'Great guy!', but sometimes you'd think: 'What an egocentric!'.
"One time, Jakub Blaszczykowski called me when he was coming back from the [Poland] national team. He said he couldn't train because of a muscle injury but would still come to the team meeting.
"Before the meeting, I went to Klopp with Kuba [Blaszczykowski] and told him what was going on. He then went pretty crazy, probably because he had only just learned about Kuba's injury at that moment.
"Zeljko Buvac [Klopp's former assistant] would often appear at such moments and say: 'Kloppo, smoke a cigarette now and calm down!'.
"He was one of the best assistant coaches I've ever worked under. But Kloppo had the balls to apologise when the way he treated someone was too much."
