Van Dijk's deal expires at the end of the season, with talks over an extension at deadlock.
He told the Daily Mail: "As long as I am calm to you guys then there is no need to panic, whatever may happen in the future. If I was worried you would see me playing a little bit worried and that is not the case.
"Maybe I will run this fully down and then if there is still no news, I don't know. I don't know at this stage (what will happen). But I don't want to create any anxiety or anything like that, I just keep my head down and focus on hopefully winning the next 10 games.
"That is my full focus: to be there for the manager, the players, the fans. So let's see what it brings and I am sure by the end of the season there will be news. But what kind of news I am not sure.
"The only thing I can say, and I have said it already many times, is that I am so proud to be the captain of this beautiful club that means so much to me and has meant so much to me in the past, as well as my family."
