Watch: Dortmund fans throw tennis balls in protest
Liverpool fans are not walking alone when it comes to staging protests against high ticket prices.
During Borussia Dortmund's 3-1 German Cup quarterfinal victory over Stuttgart on Tuesday, Dortmund fans boycotted the first 20 minutes and threw tennis balls onto the field upon taking their seats at Stuttgart's Mercedes Benz Arena. Play had to be stopped over the protest, which is reportedly in response to ticket prices for the day's game. A quarter of Dortmund's allocated tickets cost $79, while the club reportedly charged $43 for the cheapest seats and $22 for standing-room places.
The fans also hung a banner that, translated, reads "football must be affordable."
