The £12m signing is without a goal in 21 months but Hughes is confident his move from West Brom to the Potteries can still pay off.
"There's always a decision to be made if Saido's not starting," admitted Hughes. “I've got the option of Crouchy to come on and sometimes Crouchy is the best option to disrupt the opposition.
“Sometimes Saido's style and traits are more similar to the guys he would be replacing.
“On occasions, he will get disappointed that I go with Crouchy. But in fairness you can't argue with what Crouchy is doing from the bench at the moment."
Hughes insisted: “We all feel once he gets one, he will get a hatful.
“It's just about waiting for that dam to burst. We've got him on a long contract. He's still a relatively-young player.
“He's very much at the beginning of his career. There's more to come from him."
Meanwhile, Hughes insists Charlie Adam is not for sale.
The Scotland midfielder has admitted frustration over the lack of action he's seen this season.
“We still need to look at our own situation and managers and clubs will always be a little bit selfish in that regard," said Hughes.
“So if we don't feel it's appropriate, we won't be able to do that, even though we have acknowledged Charlie is frustrated because he wants to play more."
