The England international required surgery in the off-season, but his recovery hit a setback after he tore a muscle during his rehabilitation.
As a result Barry has not featured for the defending Premier League champions this season, but has revealed he is closing in on a return for Roberto Mancini's side.
"I've had two outings with the Elite Development Squad now - 45 minutes against Middlesbrough and 80 against Liverpool and I felt a lot better in the second game so things are progressing nicely," Barry told the club's official website.
"I had a double hernia operation which meant an initial four weeks out, but then I tore a muscle in rehab which set me back a little bit, but I don't think I'm too far off now - touch wood! I'm just taking things one day at a time but I'm feeling quite strong again which is really good.
"The medical team and sports therapists will have a discussion, though I'm not asking too many questions. I had a comeback date prior to the muscle tear, but things don't always go to plan."
