Commons ended his international career in May to focus on his family life and his club football with Celtic.
Scotland boss Gordon Strachan has kept the door open for the 30-year-old and Commons is not ruling out making a dramatic U-turn to play for the national team again
"I never left on bad terms. If there was an opportunity to return in the near future where I felt I could offer something to Scotland I'd certainly think about it," said Commons
"I always keep an eye on the results and who's playing, I always wish our boys the best. But at this moment in time I'm just concentrating being the best I can be for Celtic.
"A lot of people do have second thoughts, and I think when I am playing the way I am I think I could offer something.
"I'm 30-years-old now and I think that the little time that I do get to spend with my family, and go away on holiday and stuff like that, it's benefited me more and I am putting in better performances week in, week out for Celtic."
