A section of Borussia Dortmund's fans will reportedly boycott part of the club's German Cup fixture against Stuttgart on Tuesday evening in reaction to inflated ticket prices for the match.
German outlet DW Sports reported 25 per cent of tickets for the away fixture cost fans more than €70 (£54), and a group known as the "Kein Zwanni" will boycott the opening 20 minutes of the clash in response.
