The Gunners striker is back in action after a back injury.
It comes just a few days after defeating Stoke City and Arsenal boss Arsene Wenger has been putting his first-team players through their paces this week.
Arsenal's Chuba Akpom celebrates scoring their third goal
But there was also one very interesting participant, who has not been involved with the Arsenal first-team as regularly as he would have liked this season.
Arsenal had great hopes for striker Chuba Akpom. He was compared to Ian Wright by many but has failed to live up to that billing in recent times.
But he was doing his best to catch the eye in the session at London Colney.
The 21-year-old, who spent last season out on loan at Hull City, has played just once this season. He featured in the 4-0 win against Nottingham Forest in September but he suffered a back injury later that month and has been out since.
Now he is back and training with the first-team, finally hoping to turn his good under-21 form into first-team appearances.
Arsenal fans would certainly love it if Akpom did finally come good.
