The section was blown wide open last night when the Hoops picked up their first Champions League points of the campaign with a 2-1 win over Ajax and, coupled with the draw between AC Milan and Barcelona, leaves Neil Lennon's side in a far more positive position.
Holland hopeful Van Dijk reckons it is still possible for Celtic to qualify for the latter stages of the tournament again - especially if they get a result in his homeland in a fortnight.
"We are capable of going to Amsterdam and getting a win, definitely," said the defender. "I think anything is possible now.
"Of course we can qualify. But we just want to take it one game at a time. We felt that this was an important game and we are happy to get all three points. But we can definitely do the same in Holland.
"We have shown I think we can compete at this level. We will go to Amsterdam feeling confident."
There were suggestions before last night's game Dutch manager Louis van Gaal was to be among the observers at the encounter, with Van Dijk coming close to forcing his way into the senior squad for full international honours.
The player has maintained that he won't be distracted by ambitions of making it into the Holland squad, although he has acknowledged it will be the arena of the Champions League where he is measured.
"I do think the Champions League games are the games where people at home will look to see how I am playing and judge me in this environment," he said.
"Because of that it does feel good when we beat a team from Holland. We are a good team. We have good players. I always felt this was the right move for me.
"I don't think I can give my opinion about whether I am ready for international football. All I can do is play my games and focus on Celtic. It isn't something that I am thinking about.
"When you decide to move club then you always think about what might happen, is the move is a good one. It has been going very good for me so far and I am pleased. I don't want to look too far ahead. I am happy here just now."
Van Dijk has surprised himself at the way he has made the transition into top-flight European football.
The 22-year-old arrived at the club this summer from Groningen and has quickly established himself at the heart of the Celtic defence, and impressing so far in the demanding Champions League environment.
"It has been something new for me," he said. "But it has been very good for me. I was always confident I could play at this level because I know what I am capable of, but in some ways I think I have surprised myself actually.
"I have settled quickly and I feel that myself and Efe Ambrose have an understanding. He is a good guy off the pitch and on the pitch we really understand one another."
Despite getting one over Ajax last night, Van Dijk did not savour the occasion any more simply because it was a team from his homeland.
"The only thing is that they are Dutch but I have no connection to Ajax, so it wasn't extra special or anything like that," he said.
