During his time at Chelsea, Madueke made 92 appearances in all competitions, scoring 20 goals and providing nine assists. He joined Chelsea from Dutch side PSV in January 2023 and has since become a familiar face in the North London club.
Arsenal's manager, Mikel Arteta, expressed his excitement about Madueke's arrival, stating that he is an "exciting and powerful young player" who will bring "consistently high quality" performances to the team.
According to reports, the transfer between the two London clubs cost Arsenal around 50 million pounds, a profit for Chelsea who signed Madueke two years ago.
Madueke shared a heartfelt message on Instagram, thanking his former teammates, manager Enzo Maresca, and the Chelsea fans for their love and support during his time at the club.
He also expressed his gratitude for the opportunities he had at Chelsea, including featuring in five of the club's seven Club World Cup matches in the United States.
