The teenager became a vital part of the Liverpool team last season.
Sterling has been one of Liverpool stars during the Brendan Rodgers era at Anfield after being handed his first-team debut by Kenny Dalglish towards the back end of the 2011/12 season.
The 19-year-old was used heavily towards the start of Rodgers's first campaign in charge and suffered a dip in form after showing some promise, and finding the net against the likes of Reading and Sunderland, but last season the pacey winger demonstrated his versatility and became an integral part of a team that finished just two points behind Manchester City.
Last season he scored a total of nine league goals, and scored in crucial games against the likes of Arsenal, Southampton and Manchester City as the Reds put together their best title challenge since 1990.
And after being selected as part of Roy Hodgson's England squad for the World Cup in Brazil, Sterling told the Liverpool website that he needs to raise his game once more.
He said: "I've still got to prove myself; the manager has brought players in that are all in similar positions to me, so I've just got to keep working hard, show the manager what I can do and try not to take my foot off the gas, pressing for a place in this team.
"It's a top football club with top players, who come in to compete and do their best every day. That's been no different so far [in training].
"There is definitely much more to come from me. I just need to keep working hard and hopefully I can get into my full stride this season and try to do the best for the football club."
New signings such as Adam Lallana from Southampton and Lazar Markovic from Benfica are likely to increase the competition in that area of the field for Sterling, which he has acknowledged, whilst fellow youngster Jordon Ibe may be pushing him for a place.
Along with the desire to take that final step in the Premier League, along with the competition, Sterling has all the motivation he needs to find yet another level in a Liverpool shirt.
