Beşiktaş have completed the transfer of Leandro Trossard from Arsenal, with the club confirming a deal worth 18 million euros for the 31-year-old forward. The move gives Beşiktaş one of the most significant signings in the club’s recent history and places the fee among the largest ever paid in the Süper Lig.
The club’s announcement also detailed the structure of the deal. Trossard has signed a three-year contract that includes six equal installments, with three guaranteed years and a one-year club option. That level of commitment signals how strongly Beşiktaş view the Belgian attacker as an immediate addition rather than a short-term depth piece.
Why the transfer matters
The 18 million euro fee is not only a major outlay for Beşiktaş, but also the second most expensive transfer in the club’s history. In league terms, it ranks ninth-highest in Süper Lig history. For a team looking to strengthen at the top end of the pitch, that is a clear statement of intent.
Trossard’s profile helps explain the investment. He began his career in Genk’s academy, spent loan spells at Westerlo, Lommel United and OH Leuven, and then established himself at Genk before moving on to Brighton and Arsenal. Across 521 official matches, he has produced 138 goals and 78 assists for 216 direct goal contributions, underlining the kind of end product Beşiktaş are buying.
His main position is left winger, but he can also operate behind the striker or as a center forward, which gives Beşiktaş some tactical flexibility. That versatility should make him useful in different attacking setups, especially as the club looks to add proven quality with a player who has already performed in multiple European settings.
What happens next
Arsenal allowed Trossard to travel to İstanbul for medical checks and the formal steps needed to complete the move. The club also said it would issue a new update when the transfer is finalized, but the agreement on the permanent transfer and the financial terms is now in place.
Trossard’s market value peaked at 38 million euros in 2023, which adds more context to Beşiktaş’s move. Even at 31, he arrives with a strong record and a versatile skill set, making this one of the clearest high-profile additions of the summer for Beşiktaş.
