Brentford

Mousinho was signed by Brentford manager Martin Allen during the 2005–06 season, having returned from the United States where he had been studying and playing football at the University of Notre Dame. He was recommended to the club by Allen's son, having previously played for Chesham United. Mousinho made his Brentford debut on 18 October 2005 in a 1–1 draw against Oxford United in the Football League Trophy, playing the full 90 minutes. He made his Football League debut two months later, appearing as a 76th-minute substitute in a 4–1 away win over Tranmere Rovers on 17 December 2005. Mousinho joined Conference National club Woking on 9 November 2005, on a short-term loan intended to provide first-team experience. He did not play any matches for Woking and returned to Brentford after just two weeks. He was subsequently loaned to Isthmian League Premier Division club Slough Town, making his debut in a 2–1 away victory over Fisher Athletic, and scored his first goal for the club in a 3–2 victory over Bromley; Mousinho's goal came in the 58th minute as Slough came from two goals behind to win the match. In April 2006, he joined Conference South club Yeading on loan, where he made six appearances. Martin Allen described the series of loan spells as "positive" and "definitely not the end of his time at Brentford". Mousinho featured more regularly during the 2006–07 season.

Portsmouth

Mousinho was appointed head coach of League One club Portsmouth on 20 January 2023, marking his first managerial role. He signed a "long-term contract" with the club. Portsmouth chief executive Andrew Cullen stated Mousinho's leadership and motivational skills were key factors in his appointment. His first game in charge was a 2–0 victory against Exeter City at Fratton Park on 21 January 2023. At the time of his appointment, Portsmouth were positioned 15th in League One; the club went on to finish the 2022–23 season in 8th place after concluding the season with an 11-match unbeaten run. Portsmouth's unbeaten run extended into the 2023–24 season and, after guiding the team to 13 points from the opening five matches, Mousinho was named EFL League One Manager of the Month for September 2023. He received the award for a second time in February 2024, after securing four wins from an unbeaten run of five matches, further consolidating the club's position at the top of the league table. Mousinho was named EFL League One Manager of the Season for 2023–24 at the EFL Awards on 14 April 2024. Two days later, Portsmouth secured promotion to the EFL Championship after being crowned League One champions. A month into the 2024–25 season, on 20 September 2024, Mousinho signed an extension to his long-term contract with Portsmouth, alongside sporting director Rich Hughes. The duration of the extension was not disclosed. After failing to win any of their first nine league…

Mousinho spent the first decade of his senior career primarily being deployed as a central midfielder. During his time at Brentford, he also provided cover at right-back. He transitioned from midfield to central defence during his time at Burton Albion and featured in both positions during the 2016–17 season. Mousinho's leadership skills were consistently noted, having served as club captain at both Burton and Oxford United.

Born in Isleworth, Greater London, Mousinho is of Portuguese descent, with his father's side of the family originating from Lisbon. He grew up supporting Tottenham Hotspur and cited Darren Anderton and Teddy Sheringham as his footballing heroes, influenced by the attacking football Tottenham played during the early 1990s.
