Sigurdsson is scheduled to discuss his future with Hoffenheim's newly-appointed coach Markus Babbel before the end of the season.
"I think he's going to give me a call later this month," Sigurdsson said. "I'm on loan until the end of the season but I don't want to go back and sit on the bench.
"Playing in the Premier League, you're not going to turn that down when you're sitting on the bench in Germany.
"I watch the Premier League and Match of the Day in Germany. I took my Sky dish with me, so I knew Swansea played good football but once I came over, I could see it was a bit better than what I expected."
