The No.5 was recruited during Klopp's first summer transfer window at Anfield.
Discussing his experience of the bond that the boss forges with his players, Wijnaldum explained why the personal touch makes such a difference.
“The manager has had a big influence on me," he told liverpoolfc.com. “He has brought the club back to where it used to be and he brought his vision to the club, and I have to say his vision fits the club.
“The players adore him, of course, because he cares about the players and he is a good coach, a coach who improves his players and he is a great person to work with.
“We have also had a lot of personal conversations and he has become a really important person to me. He knows a lot of things about me that other coaches don't know. We have a really good player-coach relationship, as well as on a personal level. He is an important person to me in general."
