On 1 January 2017, it was confirmed by Real Betis that Chelsea had recalled the Belgian. With manager Antonio Conte unsure whether Musonda was to stay with the Blues or be loaned out, interest arose from many clubs around Europe, including Roma. However, after the conclusion of the January transfer window, Antonio Conte confirmed in a post-match press conference preceding Chelsea's 1–1 away draw with Liverpool, that Nathan Aké, Kenedy and Musonda would be staying at the club for the rest of the 2016–17 campaign. Musonda made his debut for Chelsea on 6 August 2017 in the 2017 FA Community Shield against Arsenal, coming on as a substitute after 84 minutes. He made his first starting appearance for the club in an EFL Cup tie against Nottingham Forest, scoring the third goal in a 5–1 victory on 20 September 2017.
