Bartley is pleased that his efforts at Rangers last season have been rewarded this summer.
"It was a big honour and a privilege to come back and be part of the first team," Bartley told Arsenal.com. "Just being in and around the dressing room is great and I have to thank the boss for that. Now I want to push on from here.
"It has been good so far and great to get away with the first team on tour. It's been nice to get a bit of game time with them to try and get my sharpness back.
"I just tried to give 100 per cent in every game I played. I just had to stick to the gameplan and play how I normally do - hopefully I have done well."
