After being included among the senior squad by Roy Hodgson in September, Sterling received his first cap two months later during a friendly with Sweden.
The teenager described the occasion as a 'dream come true' and pledged to progress further for the Three Lions.
"It was a good thing for me to be called up and make my debut. That was obviously a dream come true," Sterling said.
"As a 15-year-old I can remember sitting at home and praying to get an U16 call-up, so to be getting a senior call-up a few years later was one of the best things that ever happened to me.
"So obviously I want to keep driving on and do a bit more. It's 100 per cent going to be England from now on."
