The former striker has suggested there may be a "changing of the guard" in European football on the back of a successful season for German clubs in the Champions League
The two clubs will face one another in the Champions League final after seeing off Barcelona and Real Madrid respectively and the former Germany international, who is now the general manager of the national side, has tipped a power shift in European football.
“Of course, Bayern and Dortmund stand out particularly. However, if one compares all of the leagues, the Bundesliga is also in position one in terms of the quality of games,” he told Kicker.
“Investments that were made by the DFB 10 years ago, in infrastructure, in training the coach and the players, bear fruit on a wide scale.
“Despite the euphoria, I’m cautious, but it might be a spark, and perhaps the beginning of a changing of the guard.
“The fact that Bayern Munich have reached the final three times in the last four years is no coincidence. Football [in Germany] has evolved continuously and on the international level. This must now be confirmed in the coming months and years, but I’m quite optimistic.”
Bierhoff then waxed lyrical about Bayern and Dortmund's style of football, stating that their brand was the perfect representation of the German game.
He added: “I’ve always said to the DFB, we have to deal with the question of what comes after Barcelona. Both teams (Bayern and Dortmund) have shown what our playing style offers: the German virtues such as discipline, athleticism and strength, combined with our high technical skills of the players.
“[It is] the result of the high quality of the players as well as coaches and club officials regarding the entry and compilation of the teams.”
