Huijsen is currently on loan at Roma and he has impressed in his loan stint at the Giallorossi. Daniele Longo has reported that while Roma are interested in keeping the player at the club for another season, it would only have to be a loan deal. That possibility is difficult, but not impossible.
But regardless, the likelihood is that Huijsen will depart Juve at the end of the season. Dortmund have been keeping tabs on the Dutchman for multiple weeks now and they are aware of interest from other clubs in the talented young defender. They want to be quick in beating competition for the player and are already preparing an offer for him.
Juve want a fee of around €25 million and €30 million for the 19-year-old, who seems fairly likely to leave the Bianconeri in the summer. Whether that would be on loan or on a permanent basis, that remains to be seen.
