Peterson signed for Liverpool in January 2011 from Swedish side A Savedalens IF. He made his debut for the Under 18s in the 2010-11 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 2011-12 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. He also featured in the NextGen Series third place play-off tie against Marseille.
Now operating further up the pitch, often in a wide forward role, in the 2012-13 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 times- seven of which came in the NextGen Series. Peterson kicked on in the 2013-14 U21s season as he netted all three of Liverpool's goals in their four pre-season friendlies, with goals against the Glentoran, Hearts and Bologna first teams.
On 28 November 2013, his birthday, Peterson was sent out on loan to fellow Merseyside club Tranmere Rovers, in a youth loan spell which would last until 1 January 2014. On 1 January 2014, he signed a contract extension with Liverpool. He completed the U21s season at Liverpool with 6 goals and 15 appearances to his name. He went on to appear as a substitute in the Liverpool first team's post-season friendly win over Shamrock Rovers on 14 May 2014. On 16 July 2014, Peterson came on as a second half substitute in Liverpool's pre-season match away to Brondby, and netted a tap-in in the 49th minute after good work from Jordon Ibe. He scored again in Liverpool's next pre-season match, away at Preston- firing the winner in a 2-1 win. After the game, manager Brendan Rodgers confirmed he would now take Peterson on Liverpool's pre-season tour of America, with the Swede- along with most of the club's younger players- having initially failed to make the cut.
On 27 August 2014, Peterson sealed a permanent switch to Dutch side FC Utrecht.
