Bundesliga leaders Bayern Munich handed out a 6-0 thrashing to hosts Hoffenheim on Saturday but the game was marred by an offensive banner unfurled by visiting fans.
Bayern moved four points clear at the top of the table but the match was at risk of being cut short when the Munich club's fans displayed the banner insulting Hoffenheim investor Dietmar Hopp in the 79th minute.
The referee ordered the teams into the tunnel and some Bayern players, as well as the entire club leadership, walked to the stands and urged fans to take it down immediately.
After a 20-minute interruption both teams came back onto the pitch and ran down the clock without playing competitively, ending the game with an ovation for Hopp and with Bayern CEO Karl-Heinz Rummenigge by the billionaire's side in a show of solidarity.
Hopp has been a lightning rod for some German fans, who oppose the way he used his wealth to help Hoffenheim climb through the lower leagues to the Bundesliga with consecutive promotions more than a decade ago.

"I am deeply ashamed for the behaviour of these people. That is inexcusable. It is the ugly face of football," Rummenigge told reporters.
"I have apologised to Dietmar Hopp. We have filmed everything and these people will be held accountable. The way these people behaved today they have absolutely no place in a football stadium."
