The defender joined up with his Dutch teammates after helping the Reds beat reigning champions Manchester City 3-1 at Anfield on Sunday to open up an eight-point gap over second placed Leicester City.
Asked whether establishing such a commanding lead made it feel like this season could see Liverpool end a 30-year wait for top-flight glory. he replied: "I'm not going to say that [it feels like Liverpool's year].
"It's something for the media. For players the main thing is we focus on the game ahead of us.
"For me personally it's Northern Ireland, it's a tough task. What happens with Liverpool in the future we'll see, we have no influence on it, the season is so long. My focus is on the next game, at the moment that's [with our] national teams."
