"This is the recipe that helped us make millions in the transfer market"

Read the exclusive interview with Dortmund's managing director, Carsten Cramer, about the big changes the club underwent - and how they ended up being one of the most successful top European clubs on the transfer market.

A misguided financial strategy, including paying huge transfer fees and salaries for mid-market pros, brought Borussia Dortmund close to bankruptcy.

Hiring people with a passion for Dortmund and a different approach to the transfer market helped turn things around.

Today, Dortmund are a serious title contender and a Champions League knockout stage regular, with players being sold for far greater prices than they were bought.
