The Reds are keen to bring the 17-year-old centre-back to Anfield this summer, but Bayern Munich, Ajax and PSV Eindhoven are all keen on the Dutch under-19 star, while Sampdoria are understood to have bid €2.5m (£2.25m) for him in January.
After a 2017-18 in which he made his first-team debut with seven matches in the Eredvisie, Van den Berg enjoyed a breakthrough year at Zwolle last season, playing 16 Eredivisie games under former Manchester United defender Jaap Stam, helping them to a 13th-place finish in the Dutch top flight.
The defender would go into Liverpool’s Academy setup initially, playing for the under-18 and under-23 sides, with a view to progression to Melwood should he impress at that level.
