The Scotland global captained his country during their 1-0 friendly defeat by the Netherlands on Thursday (9 November), and recently signed a new six-year contract with Brendan Rodgers' men.
Van Dijk also praised Kieran Tierney, who made his debut alongside the Dutchman has risen to captain Scotland.
Tierney is just 20 but caretaker manager Malky Mackay has chosen him to skipper the side against the Dutch in the absence of regular captains Scott Brown and Darren Fletcher.
"I can remember the day he made his debut at Dundee away and since then he's been progressing every game, I think". He was the captain of his country and that's very special at 20 years old. "It's good to see". "Celtic is an fantastic club for him as well and I don't think there is any rush for him to leave".
The likes of former Celtic striker Tony Cascarino has downplayed their run on the account of his perception of the standard of Scottish football but van Dijk labelled that unfair.
The 26-year-old Netherlands worldwide joined the Hoops from Groningen in 2013 and played for the Glasgow giants until 2015 before moving to Premier League outfit Southampton for a transfer fee reported by BBC Sport to be worth £13 million.
"It's unbelievable", he said.
"It doesn't matter if it's Scotland or anywhere else, it's an fantastic achievement and people don't really understand how big it is".
"I have played it a couple of times, maybe I'm a bit more used to it as a back five, but wherever I'm told to play, I will try my hardest", added Tierney, who has also played at right-back for Scotland. "Why that group can't go on and get 50 caps each I do not know, if they keep that belief and the club atmosphere in there".
