The 22-year old left-back, on loan from Tottenham, will play his final Black Cats match against Southampton on Sunday and has been given some encouraging words by Di Canio who feels he has a very bright future.
"He's got a great future in front of him," said Di Canio. "He's a powerful guy. The strength and elasticity he's got mean he can run forward with the ball and beat people easily.
"It's obvious he can play at the top level, but everybody has to improve.
"In my opinion, he can improve a lot defensively. He's an attacking-minded left-back, but he has to improve a lot defensively.
"People have to realise there are two phases in the game - possession ball and non-possession ball. It's crucial to be good in both situations.
"I don't want to say he's not very good when we're not in possession of the ball, but he can improve a lot. He can improve the timing of his tackling and he needs to learn when and how to be aggressive.
"But everybody can improve, and he's only 22.
"It's easy to talk about his quality, but if we don't tell him he has to improve, he's probably never going to."
