He made his debut for the Under 18s in the 2010-2011 season, however he was to only play the one match for the Under 18s that season as he played more frequently for the Under 16s. During the 2011-2012 season, operating mostly as a midfielder, Peterson figured for the Under 18s far more prominently, and produced some eye-catching performances from the centre of the park.
He was one of the stand-out performers for the side, netting five goals in 22 games.
His good form brought him to the attention of Reserve team coach Rodolfo Borrell, who used the young starlet as a second-half substitute in the Under 19s NextGen Series tie against Molde FK. He also featured in the NextGen Series third place play-off tie against Olympique de Marseille. Now operating further up the pitch, often in a wide forward role, in the 2012-2013 season, Peterson continued as one of the U18"s star players.
He featured 23 times and scored nine goals and also made his step up to the U21s, for whom he featured 13 timesseven of which came in the NextGen Series. Peterson kicked on in the 2013-2014 U21s season as he netted all three of Liverpool"s goals in their four pre-season friendlies, with goals against Glentoran F.C., Heart of Midlothian F.C. and Bologna F.C. 1909 first teams.
On 28 November 2013, his birthday, Peterson was loaned to League One side, Tranmere Rovers.
In January 2014 he signed an extension to his contract with Liverpool. and said he would use it to spur him on: "This is the biggest motivation boost in my career. This is the biggest I have ever experienced". He completed the U21s season at Liverpool with 6 goals and 15 appearances to his name.
On 16 July 2014, Peterson came on as a second-half substitute in Liverpool"s pre-season match away to Brøndby, and netted a tap-in in the 49th minute after good work from Jordon Ibe.
After the game, manager Brendan Rodgers confirmed he would now take Peterson on Liverpool"s pre-season tour of America, having initially failed to make the cut, along with the most of the club"s younger players. On 27 August 2014, Peterson joined Dutch club Football Club Utrecht on four-year deal.
