Birmingham manager Chris Hughton has tipped Jack Butland to cope with his rapid elevation to England's Euro 2012 squad.
Butland has been drafted in after Norwich goalkeeper John Ruddy was forced to withdraw due to a broken finger.
The 19-year-old Blues keeper has limited experience, having played just 24 games on loan at League Two Cheltenham Town this season.
But the manager of his parent club believes Butland has the temperament to cope with the pressures of a European Championship campaign with the senior squad.
"It'll be great for his experience and development, I don't think he would be fazed by it," Hughton told Sky Sports News.
"He's a mature lad, you can't get where he is at 19 as a goalkeeper without that maturity - obviously you've got to have the ability but you need that maturity and that he does have.
"It's a massive step up but the experience he'll gain working with Ray Clemence and Dave Watson and around the quality of players will be invaluable."
He added: "Funnily enough I initially didn't think too much of him, but then he went to Colombia with the (England) Under 18s and that's where he really shone.
"Then he went with the Under 21s and he's had this rise now.
"We've seen a fair amount of him at Cheltenham where he's performed very well, he went back after Christmas and it's been a great part of his development, so we're grateful to Cheltenham.
"My thoughts also have to be with John Ruddy, he's had a wonderful season with Norwich and deserved that opportunity, but they certainly have a worthy replacement in young Jack."
