The former striker made the claim after the Canaries were reported to be interested in signing Jayden Bogle, after just one season at Bramall Lane.
The 20-year-old only signed for United last summer but caught the eye in their relegation season.
“I’d be surprised if Sheffield United sold him,” Deane told Transfer Tavern.
“You have to start basing how you want your squad to develop on youth, and he’s in that category.
“He did well in a short space of time. It wouldn’t make much sense to sell him, because then they would have to go out and find the next Jayden Bogle, so I would be surprised.”
Meanwhile, Phil Jagielka has revealed that he hoped to stay on at United for another season after yesterday being named on the list of players the Blades are releasing this summer.
John Lundstram, Simon Moore and Jack Rodwell will also depart when their contracts officially expire at the end of this month.
