Arsenal have agreed a deal to transfer Belgium forward Leandro Trossard to Turkish club Besiktas, multiple outlets report. The agreement is described as paving the way for the 31-year-old winger to leave after spending about three and a half years at the Emirates Stadium. Arsenal signed Trossard from Brighton & Hove Albion in January 2023. During his time at the club, sources note he played a regular role and contributed to Arsenal’s successful 2023-24 Premier League campaign, which ended a long title wait. The Guardian and other reports reference his Premier League output last season, including goals in league matches, with one account highlighting a late winner against West Ham in May. Sky Sports reports that Arsenal confirm the move. Yahoo Sports and other coverage indicate Besiktas are expected to pay a transfer fee around €18 million, with potential add-ons, though the final structure is not detailed consistently across reports. Overall, the reporting aligns that the transfer agreement is in place and Trossard’s departure is now imminent.
