Butland has continued to earn rave reviews in each of the three Group A matches.
He said: "It has been meteoric, a fast roller-coaster ride. I had two spells at Cheltenham and they stood me in good stead for the Under-21 games.
"I would like to think that helped me get into the England squad. I really worked hard during the season.
"This tournament has been fantastic from day one. It has been a while since there was a major tournament here.
"The country has grasped that and looking forward to watching all these players play.
"Hopefully we can go a long way in this tournament and I can push on again."
