De Ligt has been linked with the Reds and the pair were together for Thursday's win over Belarus.
Van Dijk said of De Ligt: “He's obviously an excellent defender, that's clear.
“He can still improve a lot and he realises that, but playing like he does at that age is fantastic and I'm really happy to play besides him."
Earlier this year, De Ligt also stated: "Virgil is a player who has experience in the top leagues.
“Of course, you would want to learn from him. It's very helpful playing alongside him in the Dutch team.
“It could happen (De Ligt joining him at Anfield). He plays for Liverpool , a good club, but I'm not focused on them.
“I focus on Ajax and then I'll see where I end up."
