Rotherham boss Steve Evans believes the signing of Tom Thorpe is a real coup.
The Denmark international is available as a free agent following his release by Arsenal.
A move to Germany has been mooted for some time, with Frankfurt reported to be leading the chase.
No agreement has been reached, though, and Bendtner continues to generate interest from across Europe – with it possible that he could agree to an extended stay in England.
"There is no agreement with Frankfurt,” Bendtner’s representative, Tom Brookes, told Danish publication BT.
"But there are many clubs who are interested in him and we will inform you very soon where he will continue his career.
"I am sure that we will talk more about the club when the transfer is done, and that will be soon.
"I am talking to a number of clubs and we are at the closing stages of the negotiations and sorting out the last few details. But I cannot say any more right now.
"There are options in England, but there are also clubs from other countries in Europe who have tabled offers.
"We have got a shortlist of interested clubs and would like to finish the negotiations as soon as possible."
