West Bromwich Albion goalkeeper Sam Johnstone says he had "sweaty palms" when he joined up with the England squad at St George's Park.
The 27-year-old has represented England at youth levels but his last games were for the under-20s in 2013.
"I was so excited, even though I knew a lot of the lads and a lot of the staff," he said.
"I've not been to St George's for a few years in an England squad. This is the senior team, it is the biggest one."
He added: "The lads are great and the staff are great and I have settled in straight away.
