Arsenal faces a significant setback as Edu, the club's sporting director, is set to leave his position. The Brazilian has been instrumental in the team's progress under manager Mikel Arteta and is expected to join the network of clubs owned by Evangelos Marinakis, the owner of Nottingham Forest. Edu's unexpected exit will mark the end of his five-year tenure in Arsenal's senior management, and it will mean that Arteta will lose one of his key supporters. The two have developed a strong working relationship, and Edu's departure will require Arsenal to reassess its strategy moving forward. The exact timeline for his exit has yet to be determined.
