The 24-year-old has stated that he would be interested in a move to Italy.
“He wants out and it is not an issue anymore,” said Borussia coach Lucien Favre.
“He absolutely wanted to leave us in a precarious situation. Now he can not act as if nothing has happened,” said Borussia director of sport Max Eberl.
Bradley has recently been linked with a move to Italian side Napoli.
