DFB president Fritz Keller has warned that any continued domestic domination by Bayern Munich would not be beneficial to the club or to German football in general.
Keller, who took over the job nine months ago, said there is a danger that fans will get bored if the Bundesliga and DFB Pokal do not become more competitive.
Speaking to broadcaster SWR, the former Freiburg president said: “It is certainly not conducive to football if we always have the same German champion and always the same German cup winner.”
Bayern won their eighth consecutive Bundesliga title this season, and followed that up by beating Bayer Leverkusen 4-2 in the Pokal final.
Keller has put the idea of sustainability at the centre of his tenure, and he believes having more teams lift silverware would help increase excitement levels.
“Incidentally, it also hurts Bayern if they become German champions and cup winners every year. It gets yawning boring, and no one in football wants that,” Keller said.
Bayern are hoping they can bring their domestic form into Europe next month when they seek to complete a historic treble by winning the Champions League.
