Holland great Marco van Basten has questioned Matthijs de Ligt's development at Juventus.
De Ligt has just completed a second season with Juve and was criticised by Van Basten for his performance after Holland's victory over Austria.
Van Basten said, "If you look at how many times (Maarten) Stekelenburg has to play by throwing the long ball, then they can't build, you realise that something is wrong.
"De Ligt is a central defender and needs more leadership. Hhe has to make himself heard, lead the department and instead he just chases his man, leaving a hole.
"He went to Italy to learn how to defend but I don't think he has learned much."
