Matthijs de Ligt's contract with Juventus will carry a buyout clause from 2022.
The Holland defender's deal runs to 2024 and it's emerged the clause will come into effect from June to the tune of €150m, says AS.
The news arrives just days after De Ligt's agent Mino Raiola touted his client to AC Milan.
Raiola said, "...watch out: Matthijs could also leave Juve at the end of this term. The market works like this."
De Ligt is in his second season at Juve after joining from Ajax.
