Arsenal have agreed on a transfer fee to sell Belgium forward Leandro Trossard to Besiktas.

The 31-year-old has received permission to travel to Istanbul to undergo a medical examination.

Trossard, who remains under contract with the Gunners until 2027, joined the club from Brighton for £21m plus add-ons in January 2023.

“Negotiations have commenced with professional football player Leandro Trossard and his club Arsenal regarding his permanent transfer,” the Turkish Super Lig side said in a statement.

He has scored 36 goals and registered 34 assists in 174 appearances at Arsenal, helping Mikel Arteta’s side win last season’s Premier League title.

Trossard served as a key player last season for Arteta, starting in the Champions League final defeat by Paris St-Germain and making 21 appearances in the league.

Belgium reached the quarter-finals of this summer’s World Cup, with Trossard starting all six games and scoring twice.
