Hart, who is now Charlton Athletic's academy director, believes Zaha has the pace and strength required to thrive at the top.
"I do. I think he's got great attributes - he's still got a lot to learn, I imagine he would say that, but there's enough of a basis there to say he could do very well. In the short time from April, when I last saw him, to September [playing against the senior Charlton side] there was a definite difference. He's grown from a young man's body into a man's body. He was more muscular," he told the Guardian.
