Borussia Dortmund supporters will stage a walk-out for the first 20 minutes of Tuesday's German Cup clash against Stuttgart in protest against ticket prices.

Fans of Thomas Tuchel's side are angry at being charged €19.50 (£15) for standing tickets and €38.50 (£29.60) for the cheapest seats.

The 'Kein Zwanni' campaign, which translates into 'Don't pay more than €20', was set up in September 2010 to fight against high ticket prices.

Marc Quambusch, a Kein Zwanni spokesperson, told Der Westen: 'We will not go into the standing section for the first 20 minutes,

'This also means: No support! We won't even try to grin and bear it, but rather show that you just can't do this.'

Stuttgart chairman Bernd Wahler admitted the Cup clash is a chance for his side to generate funds with his club yet to sell out for a single Bundesliga game this term.

'We need more money. And it's an option to take in a bit more in such a match,' he said.

Dortmund's plan comes after Liverpool fans announced they will walk out of Anfield after 77 minutes of Saturday's game against Sunderland in a protest against an 'unacceptable' ticket price hike.
