The reigning European champions announced the arrival of Harvey Elliott from Fulham after the 16-year-old Englishman’s youth contract expired with Scott Parker’s side. Due to the nature of the deal, Fulham are hoping that Liverpool will be ordered to pay a record tribunal fee of more than £10million when the matter is concluded. Elliott became the youngest player to play in the Premier League, aged 16 years and 30 days when he made his league debut after coming on as an 88th-minute substitute in a 1–0 away defeat to Wolves on 4 May 2019.

Elliott became right away part of Liverpool's first team on his arrival and featured in the US tour in the 2019/20 pre-season. At 16 years, 5 months and 22 days Elliott became the second-youngest player in the club's history to make his debut, when he featured against Milton Keynes Dons in the Carabao Cup on 25 September 2019. He played two more ties in the competition as well as three games in the FA Cup and made two late substitute appearances in the Premier League. He also excelled at reserve level in both Premier League 2 and the UEFA Youth League. In order to gain more first team experience, a deal was agreed on 16 October 2020 for Elliott to join Blackburn on loan for the remainder of he 2020/21 season. In February 2021 Liverpool were ordered to pay £1.2m initially to Fulham for Elliott by the Professional Football Compensation Committee. Plus £500,000 when he signs two professional contracts. First team appearances could take it to a max of £4.3million. Fulham have a 20% sell-on.
