The 20-year-old has impressed while on-loan at Hillsborough and Megson is keen to extend the loan for the rest of the season or sign the keeper on a permanent deal.
“When loan players are successful then that pushes the case for them to go back to their clubs or somewhere else,” said Megson in the Sheffield Star.
“It’s always a worry. We have half a dozen in that situation.
“I’d love to be able to sign Ben but we have to wait and see what the circumstances are, both at this club and at Stoke.
“Hopefully, we can do something with Ben. He’s another we’d like to keep.”
