EPL: Paul Merson names player Arsenal shouldn't have let go

Arsenal legend Paul Merson stated that the Gunners made a mistake by allowing Leandro Trossard to leave, as he was sold to Turkish club Besiktas. Merson described Trossard as a clever player with experience in big games. Arsenal replaced Trossard with Christos Tzolis, but Merson believes Trossard should have remained at the club.
