Arsenal have been handed a massive injury boost ahead of their Champions League game against Atalanta on Thursday as Italian defender Riccardo Calafiori has returned to training.
The Gunners star picked up an injury during the international break in a match against France, missing the game against Tottenham Hotspur last Sunday as a result.
However, Calafiori is expected to be available for selection tomorrow and should also be part of the Arsenal contingent for their trip to face Manchester City at Etihad Stadium on Sunday.
