The 56-year-old has voiced his dismay with the Bavarian club's display in the DFB-Pokal final, and admitted that BVB are now the most dominant team in the country
The Bundesliga champions beat Bayern 5-2 in Saturday's DFB-Pokal final, and the former Inter forward has admitted that BVB are now the dominant side in Germany.
"Borussia Dortmund deservedly won. We have to accept and respect that there is a team in this country that is better than us domestically at the moment," Rummenigge told reporters.
"It's not a coincidence that they have won the league title, and they have now won their first-ever double. We have to accept this, and try and do our utmost to turn things around again in the near future.
"It's not a coincidence if you lose 5-2. This was not a matter of bad luck, but we have to admit that it was an ignominy."
Bayern will be looking to bounce back in Saturday's Champions League final against Chelsea.
