The Netherlands international moved to Liverpool FC in a £75m deal from Premier League rivals Southampton in the January transfer window.
Van Dijk was linked with a switch to Chelsea FC and Manchester City but the Dutch centre-half opted to complete a club record move to Liverpool FC.
Klopp played a big role in convincing the 26-year-old to complete a transfer to Liverpool FC ahead of their Premier League title rivals.
Van Dijk has helped to reinforce the Liverpool FC defence after the Merseyside outfit made the former Celtic man the most expensive defender in the world.
Liverpool FC are on course to finish in the Premier League’s top four for the second successive season.
Speaking at his pre-match media conference ahead of Liverpool FC’s second leg at Manchester City in their Champions League quarter-final, Van Dijk said:
“Obviously that stays more in people’s minds because that is what you see, but he is much more than that,” said Van Dijk.
“He is the complete manager.
“He is a fantastic team manager, player manager as well, everyone is working hard together.
“You don’t see all the hard work we put in behind the scenes. He has shown already that he is an outstanding manager.”
Van Dijk was close to a move to Liverpool FC in the summer transfer window.
The Reds finished in fourth place in the Premier League table last term after Klopp led the Merseyside outfit to a Champions League spot in his first full season in charge.
