Randell Williams joined from Watford in 2019 and, after two-and-a-half seasons during which time he won a player of the year award, moved to Hull in 2021.  

Randell, who had previously been in Tottenham Hotspur’s academy, was nineteen and playing for non-league Tower Hamlets when he signed for Crystal Palace in January 2016. After eighteen months at Selhurst Park, and with no first-team appearances, he signed for Watford in July 2017 moving to Wycombe Wanderers on loan in January 2018. Randell made his professional debut in Wycombe’s colours on 2 April 2018 against Grimsby Town and made six appearances in total. He returned to Adams Park on another temporary transfer in July 2018 playing in another 23 league and cup games (3 goals) up until the end of December. Recalled to Vicarage Road, Randell was immediately released and agreed terms with Exeter City on 18 January 2019 making ten league appearances by the end of the season.

Randell flourished in the COVID-19 disrupted 2019/20 season and had played 43 times in all competitions, scoring five times (the first of which came in the 4-0 win over Plymouth Argyle), before the onset of the pandemic in March 2020. His scintillating performances helped City reach the play-offs, delayed to June 2020, and he was voted Player of the Year. He made another 31 appearances in 2020/21, in a season largely played behind doors, scoring four goals in the league but missing some football through injury. However by this stage Randell had declined a new contract and was to sign for Championship club Hull City on a two-year deal in June 2021.

Although he quickly appeared for Hull in the Championship, Randell failed to establish himself in the first-team and also suffered a series of injuries. After eighteen months at Hull he joined Bolton Wanderers in January 2023 for whom he made a late substitute appearance in the EFL Trophy final win over Plymouth Argyle in April 2023. With Bolton qualifying for the League One play-offs at the end of 2023/24, Randell had 32 league outings during the regular season scoring three times.
