"It has come so quick," said Butland. "But hopefully I've shown people I'm more mature than my age. That's important as a keeper, you have to be mature. You need experience under your belt but age is just a number."
If Jack Butland plays on Wednesday he would be England's youngest ever goalkeeper at 19 years 158 days, 64 days younger than Billy Moon, who kept goal against Wales in 1888.
"It's been a whirlwind year really. It started with the Under 20 World Cup in Colombia and then going out on loan to Cheltenham, which was something I needed to do.
"That helped me with the Under 21s and eventually put me forward for the Euros and Olympics."
