The BVB supremo believes that the governing body cannot continue in its current state of operation, and says the Swiss must walk away if it is to progressBorussia Dortmund general manager Hans-Joachim Watzke has joined the chorus of calls for Sepp Blatter to step down from his role as Fifa president.
Fresh allegations of corruption within the governing body surfaced recently, with former chief Joao Havelange and his son-in-law Ricardo Teixeira reportedly accepting bribes from International Sport and Leisure, a sports marketing company.
Blatter responded to the accusations by saying that he was powerless to punish the duo, leading to German Football League (DFL) president Reinhard Rauball calling for the 76-year-old to leave his post.
Watzke agrees with Rauball's view, and has called for Blatter to be removed from the presidency if he does not agree to go quietly.
"I'm joining the calls of Rauball," the 53-year-old told Focus. "The president of the DFL has called on Blatter to resign as quickly as possible.
"Either he goes voluntarily, or the Executive Committee openly expresses their mistrust in him. You must not forget what Blatter has cost Fifa.
"I think Fifa has realised that it cannot continue like this. The damage to their image is immense."
