Van Dijk has been integral to Liverpool's success since his £75m move from Southampton, helping Jurgen Klopp's men to Champions League and Premier League glory.
Manchester United legend Ferdinand is a big fan of the Dutchman and believes he is one of the best defenders to ever grace the Premier League.
Speaking on the Beautiful Game Podcast, Ferdinand said: "I love him. I think he's the best in the world right now.
"He's undoubtedly a top player but I think he's not fighting against the depth of other central defenders that was in my era.
"If we were talking about top drawer centre-halves, I could name five, six, seven, eight, nine in my era, whereas I don't think I could fill my whole hand in this era.
"And that's no disrespect [to the current defenders] but we're talking about top players here.

"Though I think in any era, he looks like a top player."
When asked to name his top five defenders in Premier League history, Ferdinand included Van Dijk, saying: "If I was naming my top five centre-halves, I think [Nemanja] Vidic, [Vincent] Kompany, [John] Terry, Van Dijk and [Sol] Campbell. They would be my five."
However, Ferdinand did add that he would be interested to see how Van Dijk played against a team which started two strikers up front as opposed to the more common lone striker system most clubs use nowadays.
"The game's a bit different now," he added. "The only thing I would like to see him [do] is play against two strikers. To see him up against two players and see him do 1v1 all the way through the ninety minutes, week to week.
"When I was playing, you were playing against two strikers all the time. Whereas now you've got one striker and two wide men, leaving the full-backs to take care of the wide men and you've got two people taking care of one player.
"So you get time to breathe, time to relax a little bit and let your partner handle him for a little bit. I would like to see him in that environment. But I think he would still handle it."
