Former PEC Zwolle coach John van 't Schip says Sepp van den Berg's inner drive sets him apart.

At just 17, former PEC defender Van den Berg became Liverpool boss Jurgen Klopp's first signing of the summer at a modest £1.3million.

Van 't Schip told the Mirror, “Look, Sepp is not the new Franz Beckenbauer. But he is a perfectionist and not many young players of his age are like that.

“He is like Van Dijk in that respect. One mistake can make him so grumpy. And he shows it too. Technically and tactically he is ready to play at the top level. He is fast, he is great in the air. But is he an adult yet? No. He was still a schoolboy when we let him train with us because we could see his potential.

“Sepp can be a big player. At this moment he is not quite ready for that step but he will be soon."
