AC Milan coach Stefano Pioli says he remains confident of Charles de Ketelaere's potential.
The summer signing has battled for form since his arrival from Club Brugge.
Pioli said, "We as a club have our own idea and our own planning. When it comes to investing in young players, everyone is happy, but then there isn't the patience needed to wait for them.
"We're talking about kids who come from different countries, from different cultures, different ways of playing, different habits...
"It's normal to have difficulties, but we are absolutely convinced that we have taken on talented, intelligent and available players."
