The new Crystal Palace boss has hailed the 20-year-old youngster as "utterly refreshing" and believes the attacker will set the game alight if he gets the chance against Sweden
The 20-year-old has been given the chance to represent England after being drafted into Roy Hodgson's squad for the friendly versus Sweden, and the new Palace coach believes he will win many new fans if he gets the chance to show what he can do on Wednesday.
"He is so unique," Holloway told the Daily Mirror. "He is an untouched, pure talent. I've never worked with anyone like him - he just wants to get the ball and beat people, however many there are, he can do it.
"Before I got to Palace, I was hearing a lot about this boy and I thought, 'Is he better than anybody else?'
"Now I have seen him. Good gracious me, it is quite unbelievable what he can do, and hopefully, a lot of fans around the country will see him still progress because it is so pure.
"Hopefully, if he does play on Wednesday, people will see that and I believe he can do it at the very, very top level.
Although Zaha has been called up to the England squad, as it is a friendly match the Ivory Coast-born forward could still choose to play for his country of birth. However, Holloway has urged the promising youngster to take advantage of the opportunity presented, and that the decision on his international future can be made at a later date.
"At the moment, I just want him to totally and utterly enjoy himself and express himself," Holloway said.
"I just want him to go and play with a smile on his face. I am never going to let my mouth write a check that his body can't cash.
"The boy is fresh, youthful, exuberant and if he can take this into a game, I think the England supporters, or the Ivory Coast supporters, will see what he can do.
"At the end of the day, this is a friendly and he can play in a friendly without committing himself and he should and that was my advice to him."
