Selling Mario Gotze to Bayern Munich has made Borussia Dortmund a stronger team, claims Stuttgart sporting director Fredi Bobic.
The 21-year-old joined Pep Guardiola's side for a fee of €37 million (£31.3m) during the summer window in a move which was largely seen as blow to BVB's hopes of wresting the title from their Bundesliga rivals.
However, the arrivals of Pierre-Emerick Aubameyang and Henrikh Mkhitaryan from Saint-Etienne and Shakhtar Donetsk, respectively, have not only filled the void left by the talented Gotze but have actually improved Jurgen Klopp's side, according to Bobic.
"Selling Gotze has made Dortmund stronger," the 42-year-old told Bild.
"They enhanced their quality and depth by acquiring Aubameyang and Mkhitaryan."
Bobic then reflected on Stuttgart's 6-1 defeat to BVB, remarking: "You don't play against Dortmund every day. The good part was that we were willing to take risks. Against a team like Dortmund, however, that can lead into a thrashing."
