Barry admits he hasn't spoken to England coach Roy Hodgson this season.
Barry said: "I have not spoken to the England manager, but I understand why I am not in it. My season hasn't really got going, and I am still getting over the injury.
"I am hopeful that if I can get a run in the team, and get some games together, I will be in the next squad.
"I am obviously disappointed because I want to play for my country but I am not ready to retire yet, and will just keep working hard.
"I am not going to say too much. I just want to work hard to get back."
