Speaking to FIFA after the match, the Netherlands captain praised his team's display, particularly in the opening stages of each half.
"I think we were outstanding for most of the match. We were very solid defensively, strong going forward, and scored five brilliant goals," Van Dijk said. "Now we're on to the next one."
Van Dijk had the task of containing Sweden's attacking duo of Alexander Isak and Viktor Gyokeres, and explained how the Dutch defence adjusted as the match developed.
"It wasn't just them. Of course, we're well aware of the quality they possess; I know them well, especially Alex," Van Dijk said.
"In the first half, right up until the water break, we were doing very well. After that, they changed their system and let Alex play freely, drifting and cutting in from the left. We struggled a bit with that, because he was always unmarked. In the second half, we changed that, of course, and went back to playing very well."
He added that facing such quality requires sustained concentration throughout.
"It's always been about seeing it through to the end against them; even when they create chances, you have to keep going, because the quality is there," he said.
It marked the Netherlands' first win of the tournament, having been pegged back to a 2-2 draw by Japan in their opener after Van Dijk's own goal had given them the lead until Daichi Kamada equalised in the 89th minute. Van Dijk felt the criticism that followed that result had been overblown.
"I think the outside world underestimated Japan a little; they're a great team. That match was always going to be difficult," he said. "Japan were unbeaten for a while; they went a spell without conceding a goal. They beat Brazil, England and Scotland. It was always going to be tough. Coming away with a draw, conceding a goal at the end – of course that leaves a bitter taste. But there were plenty of positives in that match, and that's what we've been building on this week. In the end, it's all about winning, and we won 5-1. We'll recover and move on to the next match."
Sweden head coach Graham Potter was honest in his assessment of where the match went wrong.
"Sometimes you have to have these experiences. I didn't think it was that kind of game, but we have to learn from it. We were playing against a good team. They hurt us in the wide areas. The first goal was from a long ball we didn't deal with very well," Potter said.
Netherlands striker Brian Brobbey, who scored on the day, reflected on the team spirit behind the result.
"It feels amazing to make a direct impact and I think as a team we played very well. I think everybody has a good bond with each other and we'll fight for each other as well, that's the main thing," Brobbey said.
Sweden captain Victor Lindelof took some lessons from the defeat despite the scoreline.
"The result is what it is, but I think we did some good things today that we can take with us, and obviously, another few things that we can learn from. I think the goals that we conceded are a little bit too easy. But then again, if you are not in the right position, if you lose half a meter, one meter against players like this, then they're going to punish you. That's exactly what happened today," Lindelof said.
