Watts began playing football for Cramlington Juniors before joining Newcastle United's academy in 2008.[3] He progressed through the youth academy at Newcastle, signing his first professional contract with the club in the summer of 2018.[3][5] Having played in all 41 matches for Newcastle's under-23 team during the 2018–19 season,[3] scoring six times,[3] Watts appeared on the substitutes' bench in Newcastle's final Premier League game of the season, a 4–0 away victory at Fulham on 12 May 2019, although was an unused substitute in the match.[5][6]
Loans to Stevenage and Mansfield Town
Having been included in Newcastle's 2019 Premier League Asia Trophy squad ahead of the 2019–20 season,[7] Watts joined League Two club Stevenage on a season-long loan agreement on 16 August 2019.[7] He made his professional debut the following day, playing the whole match in a 0–0 draw away at Leyton Orient.[8] He made 20 appearances for Stevenage during the first half of the season,[9] before Newcastle recalled him from the loan spell earlier than agreed on 10 January 2020.[10] Watts subsequently joined League Two club Mansfield Town on 28 January 2020, on loan for the remainder of the 2019–20 season.[11] He made seven appearances during the loan spell, scoring his first goal in professional football in the club's 2–1 away defeat to Leyton Orient on 11 February 2020.[9]
Return to Newcastle United
The League Two regular season was curtailed due to the COVID-19 pandemic and Watts returned to Newcastle upon the conclusion of his loan contract at Mansfield.[12] Newcastle applied to the Premier League for permission for Watts to be eligible to play in their remaining matches for the 2019–20 season, with Watts having already played for two different teams that season.[12] The application was successful and Watts made his first-team debut for Newcastle in the club's 3–1 defeat to Liverpool at St James' Park on 26 July 2020, coming on as a 74th-minute substitute in the match.[12][9][13]
Further loan spells
Watts joined League One club Plymouth Argyle on loan for the 2020–21 season on 24 August 2020.[14] He debuted for Plymouth in a 3–2 home victory against Queens Park Rangers in the EFL Cup on 5 September 2020.[15] Watts scored his first goal for Plymouth in an away defeat to Leyton Orient on 15 September 2020.[15][16] He was stretchered off after a collision with Gillingham striker Vadaine Oliver on 9 May 2021; he received 12 minutes of treatment on the pitch before being taken to hospital where he was assessed and discharged later that night.[17] Watts made 50 appearances for Plymouth during the season-long loan, scoring three goals.[15]

On 1 September 2022 Watts joined Peterborough United on loan until January 2023.[21] However, he had to wait until he recovered from a knee injury before making his debut in October. At the end of January 2023, the loan deal was extended until the end of the season. However, just days after extending his loan spell, Watts picked up a hamstring injury, which could hold him out for the remainder of the season.[22] At the end of the season, Watts returned to Newcastle.[23]
On 29 May 2024, Newcastle announced the player would be released in the summer when his contract expired.[24]
Watts began his career playing as a midfielder, before later being deployed in defence.[3] He is left-footed and plays primarily as a left-sided central defender.[7][29] Watts has been described as having "a strong eye for goal", emphasised by scoring two hat-tricks during the 2017–18 season when he briefly played as a striker,[4][5] as well as being praised for being "quick, focused and strong in the air".[5]
