The Manchester United youth has been brilliant since re-signing for Aston Villa on a season-long loan last summer, having joined the Villans last January on a temporary basis.
But fans of the West Midlands side have arguably only started seeing the best of him since Smith replaced Steve Bruce as manager.
The former Aston Villa boss consistently played the 21-year-old as a right-back, with Villa fans urging Bruce to play him in the middle.
And Chester, an £8 million signing in 2016 [Birmingham Mail], claims that his centre-back partner's potential is plain to see since the positional shift under Smith.
He told Aston Villa's website: "He’s been really impressive. Last season, he played right-back a lot and also picked up a few injuries so I don’t think we saw the best of him.
"But now playing next to him at centre-back, I’ve seen how good he is and how good he can be. He has all the attributes for the modern-day game.
"He’s so quick, so powerful, good on the floor, good in the air – very comfortable."
Tuanzebe himself admitted that he much prefers life in a centre-back role, telling The Birmingham Mail earlier this season: “It’s my natural position. It's where I’ve played for a long time and I feel most comfortable there. I’d only like to portray myself as a centre-back.”
The Red Devils academy graduate hasn't kicked a ball for Aston Villa in nearly a month due to injury, but the sooner he's back, the better for Smith and Villa.
