The German giants are monitoring the winger's situation and are claimed to be considering making an offer of £12 million.
Nacer Chadli celebrates scoring the third goal for Tottenham
The Times reported earlier this summer that Spurs head coach Mauricio Pochettino made his mind up to sell Chadli this summer after his poor defending allowed Michail Antonio to score a winner against them for West Ham.
While a ruthless decision, the report was backed up by the fact Chadli did not start a single league game since the Hammers loss, with 24 minutes being his lengthiest substitute appearance over the final 10 weeks of the season.
His last start, coincidentally, came in the Europa League as part of a weakened side which lost to Borussia Dortmund.

The attacker did not make Belgium's Euro 2016 squad, a direct result of his lack of regular football at White Hart Lane.
While he could choose to stay and fight for his place, a move to Dortmund would be an attractive proposition for Chadli, who will know he is at risk of spending another season on the sidelines if he cannot regain Pochettino's trust.
