Van Dijk has had remarkable success since signing for the Southampton Reds for a club record £ 75 million in January 2018.
The Dutchman has been courted by several other clubs, including City, Arsenal and Chelsea, rivals for the Premier League title.
But the central defender intended to move to Anfield months before the transfer was finalized.
“Before making the decision to choose Liverpool, I looked at all aspects of the clubs; the way you play, the teammates, the future too, “said Van Dijk.
“The city, the fans, everything has to be a big part of club membership.
“I think Liverpool at the time I made the decision was the right decision and obviously reaching the Champions League final in my first six months was obviously a big bonus and helped me a lot in my development , especially in terms of experience. “
Van Dijk assisted Liverpool in the Champions League final where he lost to Real Madrid and was a key figure in the Reds lifting the trophy 12 months later by defeating Tottenham Hotspur at the end of a season during from which he was named PFA Player of the Year.
Liverpool subsequently won the UEFA Super Cup and the FIFA Club World Cup and have six points to win the championship for the first time since 1990.
And, speaking to BT Sport, Van Dijk said of his own game, “I just have to keep doing what I do for longer. Everyone will always have their opinion, keep an eye on the little things that happen in the game, the little mistakes you could make in a game.
“I just focus on maintaining the same level I have had in recent years.
“There is always room for improvement, I just have to keep looking and keep working on it. The manager and my teammates can continue to help me get better. “
Premier League clubs are waiting to know when they can resume their activities, with players ready to resume full training later this month if the government gives the go-ahead to “Project Restart.”

Van Dijk and his Liverpool teammates have been training in isolation since the suspension of the elite on March 13.
And he added, “It’s hard not to be there and to show off our talents. Even the smallest things.
“Playing for so many fans, all the preparation for the games, training sessions, seeing the boys – we spent so much time together and all of a sudden, we haven’t been together for almost two months.
“It’s crazy and the feeling you have right now that you have never felt before. It certainly makes you appreciate football a little more. “
