On a relationship level, Klopp is successful because he treats people the way they should be treated...

"He was 100 per cent sure I could make a difference and I am on my third contract with Liverpool, so it's about giving meaning to the players and having support from the right people. He is just a good guy, I think that is the basic thing.
"Jurgen is a really kind man. Try to think about your best friend or a family member or a fantastic colleague and you are talking where you are not thinking about how you should be and you are just saying what needs to be said. That is the way I am feeling about Jurgen Klopp.
"My first visit at Melwood, we were just talking about throw-ins, normal stuff like hobbies and families, the weather and the city, so it is just fantastic to be with him when I am at Melwood.
"He would also be a really good leader in another company because he is just a good guy. He is also building relationships and creating a culture where people want to help each other and be kind.
"He called me early July and said he tried some things and they didn't work, so if you can see that your leader is willing to say he is not perfect and doesn't know everything, instead of pretending they do know everything, then it is so much easier for the players and the staff to [say the same and learn].
"People at Melwood are not working as 'I' they are working as 'we'. He is a really good manager football-wise and he takes really good decisions with his other staff.
"It is just a pleasure every time I am there in Liverpool. Every time I go to Melwood, it is like I open the door to heaven."
