The defender joined his new teammates for the opening day of pre-season on Saturday having completed a transfer from PEC Zwolle last month.
And the manager is eager to see how Van den Berg builds on the opportunity in his hands.
“He is a big talent but a young boy and we already have a good team," Klopp told Liverpoolfc.com. “He took the challenge, he really wanted to be part of this and I'm really happy for him.
“We make signings for immediately or for the future and it's always about the boys, what they make of it. The first impression here was really good and I'm happy to have him around."
