Liverpool manager Brendan Rodgers is confident youngster Raheem Sterling will not only begin this season with the impact he did last one, but maintain a higher standard throughout.

The forward, who had just three league substitute appearance to his name from the previous campaign, was handed a surprise start against Manchester City last August aged just 17.

He then started the next 15 matches in succession, during which time he also made his full England debut, and after signing his first major contract he remained a key part of Rodgers' first-team plans until injury saw his season ended in late March.

But the manager believes a summer of recuperation has been beneficial and expects even more from the player this time around.

He has already responded with goals in both of Liverpool's pre-season friendlies so far and Rodgers said: "I thought he was outstanding the other night (against an Indonesia XI).

"He's come back refreshed. He did work over the course of pre-season and was back and forward from his holidays into Melwood preparing himself well.

"He looks so fit, he looks sharp, he looks better than what he was last summer when I came in and I think he'll play a big part for us again this season.

"At 18 years of age, he has so much potential.

"If we nurture that well and he can retain his focus and mentality, he can be a big talent for Liverpool.

"I've been pleased with what I've seen from him so far."

Sterling, signed for an initial £600,000 from QPR aged just 15, was given his first-team debut by previous manager Kenny Dalglish in March 2012.

However, it was not until he was thrust into the limelight by Rodgers that he began to show true potential.

"It was a year ago when I came into the club and he came away with us on pre-season as a reserve/youth-team player, and his enthusiasm, quality and tenacity really hit me," Rodgers told

"He ended up starting the season after the West Brom game and for the first six months he was sensational.

"He ended up getting a full England cap, which shows you the impact he made at 17 years of age, and make over 30 (Liverpool) appearances.

"Towards the end of the season, there was a natural drop-off purely because of the youthfulness of him and also because of the pressure of playing for Liverpool and at the very top end of the game.

"I took him out of that, he had a little injury at the end of the season as well but I wanted to protect him and make sure he doesn't have too many miles on the clock too early."
