The Germany international has been heavily linked with a switch away from the Bundesliga giants of late after rejecting a new contract.
This has alerted the Premier League trio, and Bayern Munich, who are all said to be looking at his release clause – which is set to be around £20m next summer.
Reus is widely seen as Dortmund’s key man, and even more responsibility is being placed on him now following the exit of Robert Lewandowski.
And now Dortmund’s sporting director, Michael Zorc, has revealed that there’s no way the 25-year-old will be leaving before the new season starts and that the club will do all they can to ensure that he stays long-term:
“[We will] definitely try to keep him long term,” he is quoted by The Metro.
“Marco is not only a hugely important player for us because of his athletic performance, but also in his role as a poster boy.
“He is Dortmund-born and a figurehead for this club.”
Reus missed Germany’s recent World Cup triumph through injury.
