With his current deal set to expire at the end of the season, the Poland international is free to sign pre-contract terms with a new employer in January.
It is possible that Dortmund will look to offload him during the winter window, rather than see him walk away on a free.
Speculation has suggested that a switch to Bundesliga giants Bayern Munich is virtually guaranteed, with both sides having expressed a willingness to work together.
Lewandowski is, however, adamant that nothing has been put in place as yet and admits he would like to play in England at some stage - with Manchester rivals United and City having courted his services in the recent past.
The 25-year-old, who has netted 66 goals in the last two season and nine in nine appearances this term, told the Daily Telegraph: "I will be able to sign a contract in January, but I have never said that I will sign a contract with Bayern.
"It was a misunderstanding. It is true I had the opportunity to speak with Sir Alex Ferguson (last year), but we didn't mention the transfer.
"One day I would like to play in the Premier League. It would be a great experience."
Lewandowski came close to joining Blackburn Rovers in 2010, but Sam Allardyce missed out on his signature as Dortmund stole in to lure him away from Lech Poznan.
He added: "There was a proposal from Blackburn.
"I even spoke with the former manager. In the end, I decided that Dortmund gave me a better chance of development as a footballer."
For now, Lewandowski's focus is locked on the England national side, with Poland due at Wembley on Tuesday for a contest which could see them wreck Roy Hodgson's dream of securing automatic qualification for Brazil 2014.
Lewandowski said: "We know all about this England team and the whole team is very dangerous. As always, we have to watch out for Wayne Rooney. It's not only the task for defenders, but for the whole team, and it will be a very hard match.
"We won't be favourites and we don't stand a chance of going through, but we want to go to Wembley and allow our supporters a little fun.
"I don't know why we have good players at top clubs but we don't have a team who can play ruthless football and kill teams off. In qualification, victories and points are the most important things, not the style of play."
