Cahill said: "From the time you are a little lad you strive to play for your country, so why not put me in against Switzerland? I'm ready for it definitely.
"I think the opportunity is there for a new back four for England. I've got a little bit of age on my side and the more experienced boys can show me the ropes.
"I've come on and played, made that debut and that's a big thing after constantly thinking, 'when's it going to come?' I can learn from the boys in front of me now.
"I hope to be in the England set-up for years to come."
