The Rossoneri legend has offered the youngster words of encouragement, and feels he has the potential to become an even better player over time
The 20-year-old has been one of the revelations of the 2012-13 campaign as he has developed into an important first team member at Milan, and his good performances have not gone unnoticed elsewhere.
"I like watching De Sciglio play - how he makes himself useful to his team-mates and how he runs up and down the flank," Maldini told Milan Channel.
"De Sciglio definitely has the Milan style and the appearance of a Milan player. He has the advantage of being a versatile player. He can play on both the left and the right side.
"Physically he can still improve a lot but even when I was 20 years old I was not fully mature and was not a complete athlete. I believe he will do the same.
"There is one more thing I think he can improve on: He needs to have more of a killer instinct - in a sporting sense of course."
De Sciglio has made 19 Serie A appearances so far this season.
