Die Schwarzgelben have confirmed that the Germany international would be free to leave Signal Iduna Park should any interested party meet the fee specified in his contract
Borussia Dortmund chief executive Hans-Joachim Watzke has admitted that Marco Reus has a release clause and that the club could easily lose the attacker as a consequence.
The Germany international is one of the most coveted players in world football at the moment and has most recently been linked with Manchester United.
Watzke has refused to disclose the exact details of Reus' current deal with Dortmund, but he did concede that the club could lose the 23-year-old in the same way they lost Mario Gotze to Bayern Munich during the summer.
"Marco Reus possesses a release clause option in his current contract at our club," Watzke told SPORT1media. "He could leave our club due to that.
"He is, however, the only player in our first-team squad that has such a contract clause."
Dortmund were dismayed when Gotze departed for the Allianz Arena after Bundesliga rivals Bayern agreed to meet the playmaker's €37 million release clause.
