The Danish shot-stopper failed to make a single Premier League start for the Potters in 2012/13, as he struggled to displace Asmir Begovic from Tony Pulis' plans.
There has been a change of manager at the Britannia Stadium since the end of last season, with Mark Hughes arriving, but the outlook for Sorensen remains bleak - with England international Jack Butland having added further competition for places.
Sorensen is reluctant to spend another campaign in the shadows, at the age of 37, but admits there are no formal offers on the table for him to consider at present.
Sorensen told Onside.dk: "If there was something interesting we would, of course, look at it. However, at present there is nothing concrete.
"I'm not looking to move at any cost. There are many factors to take into account.
"If the right offer arrives we will look at it, but the option has not been there so we will have to see what happens.
"There are many things that come into play. One is whether clubs are interested, but they may also want to rotate you around. Many things need to fall into place."
