But it was only when he travelled to other parts of the globe that he was able to understand the club's sheer scale.
Van Dijk told the Mirror: “I have always said that lifting the Premier League trophy would be a dream. That dream has become reality now.
“It is hard to explain what this club means. You have to feel this club, experience it, taste it. Of course I knew about Liverpool before I came here. Who in the world doesn't?
“You have a kind of picture of the club from a distance and you imagine it is something massive.
“And yet, you are still bewildered and surprised by the sheer magnitude of the club once you sign a contract here.
“And even after that it takes time to take everything the club stands for on board."
Van Dijk added: “Never before have I been on holiday with so many people coming up to me. All day long people approached me, telling me that they were Liverpool fans.
“At one point I started counting. Eight out of 10 people who I bumped into were Liverpool fans! It was a funny experience, but the real shock came when we went to the United States for our tour.
