Former AC Milan coach Arrigo Sacchi is convinced by the potential of Charles de Ketelaere.
The summer arrival from Club Brugge is being gradually introduced by coach Stefano Pioli.
After the draw with Atalanta, Sacchi told La Gazzetta dello Sport: "He has just arrived, let's give him time because he has to learn Italian football.
"It seems to me that he moves a lot, that he often looks for depth and this is a detail that should not be underestimated.
"Very nice the assist for (Sandro) Tonali and very good (Juan) Musso to reject the shot.
"De Ketelaere has shown that he is talented, he must be cultivated and he must not be subjected to great pressure."
