American international forward Josh Sargent joined Norwich City on 9th August 2021 from German side Werder Bremen for an undisclosed fee reported to be £8.55million. He signed a four year deal. Five days later, he made his debut in a 3–0 home defeat against Liverpool after coming on as a substitute at 77th minute in place of his former Werder Bremen teammate Milot Rashica. He made his full debut on 24th August 2021 in the 6-0 thrashing of Bournemouth in the League Cup with Sargent scoring twice. He was the first American to play for Norwich's first team since Zak Whitbread.

Josh began playing with the Scott Gallagher Soccer Club in Missouri at the age of 8 and played high school soccer. He moved to Florida as part of the US residency programme. He was ranked the number 2 high school soccer player in the country.

After impressing at the 2016 Nike International Friendlies, he trained with Sporting Kansas City in the summer of 2016 and the MLS side aquired the player's acquisition rights. In October 2016 he trained with Dutch side PSV Eindhoven and the following January with German side FC Schalke 04. In September 2017 Werder Bremen announced that Sargent would join them in January 2018 and then signed a professional contract on his 18th birthday the following month.

Sargent made his Werder Bremen first team debut on 7th December 2018 against Fortuna Dusseldorf, scoring with his first touch two minutes after coming on as a 76th minute substitute. He played 81 games for Werder Bremen scoring 15 goals (plus 12 games for their second side in the Regionalliga Nord where he scored seven goals)

After being selected for the USA's Under-15s in 2013, he joined the Under-17 residency programme in Florida in 2015. In April 2017 he was selected for the USA to compete in the 2017 CONCACAF Under-17 Championships in which the USA reached the final and Josh scored five goals. He was then included in the squad for the 2017 FIFA Under-20 World Cup. He scored twice in the opening game against Ecuador, and went on to win the Silver Boot with four goals.

In November 2017 he received his first call-up to the national team and made his international debut against Bolivia on 28th May 2018. In 2019/20 he helped the USA to win the CONCACAF Nations League. At the time of his transfer to Norwich he had scored 30 goals in 48 games for the Under-17s, before scoring four in six for the under-20s and five in 16 for the senior team.

He made 29 appearances, scoring four goals, in 2021/22 as Norwich finished bottom of the Premier League.

On 9th November 2022 Sargent was included in the USA squad for the World Cup in Qatar. His inclusion came after he scored eight goals in the first 20 matches of the 2022/23 Championship season. He started the opening game against Wales, came on as substitute against England and started against Iran. However an injury ruled him out of the last 16 clash with the Netherlands.

He made 41 appearances in Norwich's disappoining 2022/23 Championship season scoring 13 goals.

In August 2023 he was the subject of an inquiry from Leeds United but was then injured scoring Norwich's first goal in the 4-0 win at Huddersfield on 26th August 2023 which will see him miss months through injury.

He was recalled to the USA squad in March 2024 for the CONCACAF Nations League semi-final clash with Jamaica after scoring.10 goals since his return in December 2023. He withdrew from the squad after being sunstituted against Stoke on 16th March 2024. After the game, head coach David Wagner hinted that he would like to keep his joint-top scorer in Norfolk to continue his measured return from a long-term ankle injury. Wagner told BBC Radio Norfolk that the striker had suffered a “knock and twist” to his ankle.

After Norwich failed to reach the Championship play-off finals, crashing out at semi-final stage to Leeds, Sargent was reported on 19th May 2024 by the Sunday Mirror as a target for Leeds' manager Daniel Farke who had signed Sargent for Norwich. The article reports that Premier League trio Bournemouth, Brentford, and Fulham are also keen on pursuing a deal for the American international this summer. Sargent had made 30 appearances for City scoring 16 goals despite being out of action for four months. His goals are even more impressive when considering that manager David Wagner reported that Sargent was struggling to complete a week's training. Sargent was called up to the provisional USA squad for the Copa America but was struggling with a niggling foot injury which made him miss their final warm-up against Colombia.

During August 2024, there was speculation linking Sargent with a move to Major League Soccer with St Louis and FC Cincinnati linked as well as Bournemouth and Brentford. City placed a £30million price tag on Sargent and he remained at the club past the 30th August 2024 deadline.
