Fabio Vieira has officially left Arsenal to join Hamburg on a permanent deal, marking the club's first completed transfer on Deadline Day. The 25-year-old midfielder, who joined Arsenal from Benfica in 2022, has moved to the Bundesliga side after spending the previous season on loan. The transfer comes as manager Mikel Arteta looks to reshape the squad ahead of the new season. Vieira’s departure frees up space in Arsenal’s midfield, allowing the team to focus on strengthening other areas. The move was confirmed by both clubs, with no further details released on potential replacements or future signings.
