Arsenal have officially agreed to sell Leandro Trossard to Turkish side Besiktas in one of the club's first major moves of the 2026 summer transfer window. The Belgian international is set to leave North London after three successful seasons, with Besiktas reportedly paying a package worth around £17 million, including performance-related bonuses. The transfer marks another significant step in Arsenal's squad reshaping ahead of the 2026/27 campaign.

The deal has already been finalized between both clubs, allowing Trossard to travel to Istanbul for his medical examination and complete the remaining paperwork. Once the final formalities are finished, Besiktas are expected to officially unveil the 31-year-old winger as one of their headline signings. His arrival also represents the Turkish club's seventh acquisition of the summer as they continue rebuilding following last season's fourth-place league finish.

Trossard leaves Arsenal after making 174 appearances across all competitions, contributing 36 goals and 31 assists. His consistent performances made him one of Mikel Arteta's most reliable attacking players, ranking among the club's leading contributors since joining in 2023. He also played an important role in Arsenal's Premier League-winning 2025/26 season, delivering crucial goals and assists throughout the title-winning campaign.

With Trossard's departure confirmed, Arsenal are expected to intensify their serch for a new left-sided attacker. Strengthening the wide areas has become one of the club's priorities this summer as Arteta looks to refresh his squad and maintain Arsenal's status as one of Europe's strongest teams heading into the new season.
