Midfielder Louie Copley has received his first senior callup, with the midfielder named on the bench as Arsenal face Club Brugge away tonight.
Josh Nichols and Marli Salmon are also amongst the substitutes.
Copley travelled with the first-team to Asia in pre-season but this is his first competitive callup.
Right-back Nichols, meanwhile, has been called up to the senior squad for the first time in the Champions League. He made his debut against Bolton Wanderers in the Carabao Cup last season.
Centre-back Salmon is named on the bench for the first-team for the second consecutive game. It is also his first Champions League callup.
