Media reports have suggested that Blues could be tempted to cash in on the highly rated England Under 21 international goalkeeper, who is currently on loan with League Two side Cheltenham Town.
"I would be surprised if there wasn't interest, or his name wasn't mentioned at times," the Blues boss told the Birmingham Mail.
"This is an 18/19-year-old goalkeeper who is a real prospect, playing for England Under 21s.
"But he is also a lad who very much showed his intentions some weeks ago by signing a long-term contract here.
"We are delighted to have him, we're delighted to keep working on his development and all that Jack has on his mind is one day representing his club between the sticks and we very much look forward to that."
