The 27-year-old has been linked with a move to Hertha Berlin recently.
“I would be lying if I said that I am no longer interested in playing in the Bundesliga,” he is quoted in the Daily Record.
“My goal is to play again in Germany but not at any price. I would only move back if everything was right for me.
“Allegedly a scout from Hertha watched me against Rangers. But I’ve only read that and no-one from that club has spoken to me.
“They would not have the power to pull me and my family away from Scotland. We feel comfortable here.”
