After an agreement was reached and all documents signed, Leandro Trossard has been announced as the latest recruit at Besiktas. The forward leaves Arsenal after completing all formalities. With the deal now official, attention turns to when the new signing will debut for his new club. Leandro Trossard had attracted interest from Newcastle, Aston Villa and Fenerbahce, but it was Besiktas who secured the agreement and completed every step of the process. A deal that once seemed uncertain is now fully confirmed. At 1.88 goals scored per game this season, Besiktas already pose a big threat. Leandro Trossard would be expected to maintain that level and give them another reliable option in attack. Alongside this, Arsenal are said to be exploring Konstantinos Mavropanos, Aaron Wan-Bissaka and Crysencio Summerville with Besiktas likewise connected to Armand Lauriente and Augusto Batalla.
