The timing of the incident is particularly notable as it occurred during Rosenior's first game in charge of Charlton Athletic. Despite the excitement surrounding his appointment, the atmosphere at The Valley was marred by the alleged behaviour of the away end, even as Chelsea dominated on the pitch with Jorrel Hato, Tosin Adarabioyo, Marc Guiu, Pedro Neto and Enzo Fernandez all finding the back of the net in the 5-1 victory.
Chelsea's FA Cup campaign ultimately ended in heartbreak with a 1-0 defeat against Manchester City in the final. Meanwhile, Rosenior's tenure at the club came to an abrupt end on April 22; his departure followed a dismal run of five consecutive league defeats without scoring a single goal, marking the club's worst winless and goalless streak in the league since 1912.
