Bayern Munich are reported to be desperate to sign the 17-year-old centre-back, Sampdoria bid £2.5m for him in January and Ajax and PSV Eindhoven are also circling.
Liverpool already have four center-backs in Virgil van Dijk, Joe Gomez, Joel Matip and Dejan Lovren, but view Van Den Berg as a player they can develop for the long term, while also recognising he has the potential to play first-team football immediately if required.
It's understood the club view the player as a similar project and at a similar stage of development as Joe Gomez when he signed from Charlton in 2015.
