The BVB chief is not impressed with the German champions' transfer strategy in the wake of the announcement that Mario Gotze will join the RotenBorussia Dortmund general manager Hans-Joachim Watzke has hit out at Bayern Munich following the news that Mario Gotze will leave for Bayern in the summer transfer window.
The newly-crowned Bundesliga champions announced on Tuesday that they have agreed personal terms with the Germany international and will match his €37 million buy-out clause to complete the deal.
Watzke is not impressed with the way Bayern have dealt with the situation, though, and has accused them of deliberately trying to weaken their rivals.
"I believe Bayern have followed the same pattern to achieve success for quite a while and weakening their rivals is part of their strategy," Watzke told Sport Bild.
"We always expect approaches from Munich for our players, regardless of their statements of solidarity.
"We try to fight them with the means we have. It's then up to the players to decide which is the more interesting prospect for them."
Gotze, 20, is a product of the Dortmund youth academy and has made over 100 official appearances for BVB so far.
The attacking midfielder's contract with the Schwarzgelben was due to expire in the summer of 2016.
