Arsenal beat Manchester City to the signing of 15-year-old Koran Thompson by offering him a full scholarship as well as a £1.1million fee to West Ham.

Despite his leadership role with the youth squads, Rosiak faces limited opportunities to break into the first team this season, especially with the depth Arsenal currently boasts in defensive midfield.
