The forward has spent almost 15 months on the sidelines due to rupturing his anterior cruciate ligament in April 2014 that saw him miss out on a spot in England's World Cup squad after earning his debut in November 2013.
The injury put his England career on hold but, after scoring twice in his first appearance under Ronald Koeman in a friendly this week, the 25-year-old aims to put himself back into contention for the national team.
"As a player, you always want to play at international level, so obviously for myself I want to try and become the player I was and obviously try and push my way back into the team," he told the Daily Echo.
"It's just a case of, first thing, playing well and feeling good in myself in the games and then hopefully something will happen.
"I have my own personal goals that I want to achieve. I always set myself a goal at the start of the season and I will just obviously stick to that, but, like I said, my main aim is to always keep improving.
"I’m very excited. I just want to keep improving as a player and keep trying to replicate what I did a couple of years ago, and hopefully I can."
