Wirtz’s 42nd minutes was ultimately Liverpool’s winner as they secured all three points in an edgy win over Wolves at Anfield.
Signed for a reported £116 million in the summer, the German’s goal was his first in 23 appearances across all competitions since joining.
Reported by ESPN, Van Dijk said of Wirtz after his role in the victory: "I was very happy for him. He played a very good game. Everyone was outstanding in the first half. It's great to see and hopefully many more to come from him.
"He's getting used to playing for Liverpool and what we want to do as a team. He's getting used to the intensity. After about 70 minutes I think he had some cramp. It's part of the game. He just has to keep going. It was an important goal for us and now on to New Year's Day.
"I think he runs almost everywhere. At times on the left, at times in the middle. He's a very intelligent player who is so comfortable on the ball. He finds space between the lines and can be very important.
"He wants to be important in terms of goals and assists. The work rate he puts in and the chances he creates is what I think is even more important. I am really pleased for him, like the rest of the team. You saw the celebrations. Everyone is so happy for him."
