Dortmund coach Juergen Klopp has spoken neither in support nor defence of the Ruhr derby boycott.
In an interview, media source Ruhr Sport said: "Your wish, so it was read in the last few days, was for as many fans as possible to boycott the game at Schalke."
To this, Klopp replied: "That is absolutely not true. I was interviewed 40 times on this issue and in the end I said that the fans are apparently not in the mood to finance [Klaas-Jan] Huntelaar's transfer."
"Now it's going all over the media, which is ridiculous. This is a topic I did not open, and I will not discuss it in the future."
The Ruhr derby between Dortmund and Schalke is always a heated match, but this fall's clash will sizzle even more due to the proposed boycott. Ticket prices for visiting Dortmund fans have been raised by 50% in recent weeks, leading many travelling supporters to consider returning their tickets. Dortmund defender Mats Hummels has already spoken out in support of the boycott of the match, which will be held on September 19.
