The 33-year-old has reportedly attracted the attention of Saudi Arabian club Al Nassr, and with his contract expiring in June he may be leaving on a free transfer.
It still remains unclear which way Reus is leaning, but for now he is focused on the job at hand with the BVB, who have slipped down to sixth position in the Bundesliga standings.
"That's what I have an agent for - to take care of these things," Reus told reporters at Borussia Dortmund's training camp in Marbella.
"Of course you look ahead. I still have half a year left on my contract, I have to think about it.
"We will have talks and see in which direction it goes. We'll see what the future brings.
"I'm here to get fit and to push the team further because we have a lot of catching up to do. That's my focus."
The Bundesliga resumes on 20 January, and Dortmund will be in action against Augsburg on the 22nd.
