The Dane's deal expires in June.
"I have set some requirements for next season." Sorensen told Tipsbladet.
"It should be something where I can see some opportunities and challenges, because I feel I have played enough matches in my career.
"Therefore, I will not join a Championship club just to get to play more matches.
"I will turn 38 years and would like my body to still be healthy after the career is over."
