The 24-year old Denmark international is currently on loan with Juventus but revealed that he would consider a move across to White Hart Lane from the Emirates Stadium if the opportunity ever arose.
"History is filled with examples of players moving between rival clubs and I can't rule out clubs due to where I might have been in the past," Bendtner told bold.dk when quizzed on the possibility.
"It might not be the best idea but if the project matches my ambitions I would have to be interested."
He added: "I still have a great relationship with London, which is a city that I adore.
"I have a lot of friends in London and there are a lot of great clubs in London, so I wouldn't rule out a return."
