The German international has been high on the transfer list of multiple clubs throughout the summer window, but both the player and his current employers had dismissed them as just rumours.
The Bundesliga club are keen to hold on to their star player and have opened negotiations to get him to sign a new deal before the end of the season, due to the special release clause that will become active in his contract next summer. The clause in his contract will allow him to leave for Dortmund for £20m.
The Bundesliga runners-up last season are going through a rough patch in the league and have failed to win any of their last four league games and are currently in 15th place with seven points from nine games.
This situation has led the club to stop contract talks with the player in order to focus on stunting the slump the club is going through.
However, the sporting director Michael Zorc has admitted that they are still keen on keeping Reus at the club, but will only resume talks after the club is in a better position in the league.
"Nothing has changed about our intentions to continue our collaboration with Marco," Zorc said, as quoted by the Express.
"But the current situation demands full focus from everybody at the club."
"Our biggest priority at the moment is to get out of this difficult situation. Everything else comes after that for now," the Bundesliga club's sporting director added.
Apart from the three Premier League clubs, Bayern Munich have also confirmed their interest in signing the German midfielder.
But the Bavarian giants' chief-executive Karl-Heinz Rummenigge is aware that relations with their Bundesliga rivals are at an all-time low after they prised away Mario Gotze and Robert Lewandowski from Dortmund in the last couple of seasons.
