Mumba made his senior debut for Sunderland against Wolverhampton Wanderers on the last day of the 2017–18 EFL Championship season, coming on as an 87th-minute substitute for captain John O'Shea, who handed him the captain's armband as he entered the field of play, making him the club's youngest ever captain for the few minutes of play remaining.[2][3] On 2 November 2018, Mumba signed his first professional contract with the club until 2021.[4] He joined South Shields on loan in March 2020, scoring in his second game, at home to FC United of Manchester.[5][6]
Mumba would play 47 games and score eight times for Argyle as they went on to win the League One title, and finished as runners-up in the EFL Trophy, with Mumba starting in the Wembley final. The majority of Mumba's appearances came at wing-back in a 3–5–2 formation, often rotating flanks with captain Joe Edwards.[13]
At the end of season, Mumba was named the Argyle fans' Young Player of the Season, his teammates' Player of the Season, and was honoured at the EFL Awards as the division's Young Player of the Season.[14][15]
Plymouth Argyle
On 21 July 2023, Mumba signed for Plymouth Argyle on a permanent basis, signing a four-year contract with the club, for a reported £1 million transfer fee. This would equal Plymouth's all-time record fee that was paid to sign Morgan Whittaker earlier that same week.[16]
On 5 August 2023, Mumba scored in his second-debut for the club, in a 3–1 EFL Championship win over Huddersfield Town, while playing on the left-wing in a 4–3–3.[17]
International career
Mumba has represented England at under-16, under-17, under-18 and under-19 level.[18] His parents are Congolese.[citation needed]
